Abstract

Strategies of risk mitigation become effective when citizens facing hazardous phenomena adopt rational behaviours that contribute to the lowering of the risk. This is more likely to occur when endangered communities share a widespread understanding of natural phenomena and their impacts. To reach this goal, educational and outreach materials are often organised around the descriptions of the natural process and its effects. Unfortunately, however, receiving correct information does not automatically grant the adoption of safe behaviours. Our teaching efforts may fail because of pre-existing biases, beliefs, and misconceptions. The identification of these biases is important to plan effective educational campaigns capable of providing the concepts that are needed to actually inform citizens' choices about natural hazards.

In this work, we present the results of an unconventional workshop on volcanic risk that we proposed to primary and secondary schools (aged 6–13) in Italy. The workshop is meant to explore the mental models that kids and youngsters have about volcanic eruptions, and it takes the form of a creative exercise. We asked the pupils to write and illustrate a story in four frames, describing the onset and outcome of an imaginary eruption. All stories were then presented to the class and always provided useful hints to spark discussion about volcanic processes and hazards. As a whole, the collected stories provide a multifaceted description of volcanic eruptions and their potential impacts as imagined by the kids. A careful analysis of this material provided several insights useful to improve future outreach material and educational plans. The workshop is simple to reproduce, even remotely, and could easily be extended to different types of hazards.

While very simple to organise, this approach grants the secure engagement of most participants and offers a very different perspective on pupils' understanding of natural phenomena.

1 Introduction

The mitigation of natural risk commonly involves educational campaigns aimed at disseminating correct scientific information among the exposed communities (Cardona, 1997; Borges de Amorim and Chaffe, 2021; Mohadjer et al., 2021). A clear understanding of how natural phenomena may unfold and eventually impact our lives is expected to favour the adoption of mitigation measures and cautious behaviour (Camassi et al., 2016; Meyer, 2009). However, the simple availability of correct information may be insufficient (Cook and Melo Zurita, 2019; Mohadjer et al., 2021). Mental models, personal experience, and emotional belief play an important role in shaping people's response to hazards (Meyer, 2009). Research conducted to explore the commitment to mitigation measures against hurricanes showed how bad habits (like leaving windows open during a tornado) can be perpetuated by a poor understanding of the physical phenomenon – in this case, the wrong assumption that building destruction is caused by the pressure difference inside and outside the house (Meyer, 2010). Mental models and beliefs constitute the magnifying glass through which laypeople will access and interpret any information regarding natural hazards (Chester, 2005; Gibson et al., 2016). Personal experience and emotions also contribute to form risk perception. Risk communication efforts should therefore take into account pre-existing knowledge and the current understanding of natural hazards in order to target the specific needs of the communities involved (Gregg et al., 2004; Lacchia et al., 2020). The comparison between experts' and laypeople's mental models highlights missing information, possible gaps, and misconceptions on both sides, and most importantly, it grants a correct identification of people's needs and expectations.

This work focuses on volcanic eruptions and their perception and targets kids and youngsters living in the Neapolitan urban area. The town is surrounded by the following three active volcanoes: Vesuvius, Ischia, and Campi Flegrei. The most recent eruptive activity in the area took place at Vesuvius, in 1944, when a lava plug obstructed the volcanic conduit (Sbrana et al., 2020, and references therein). Since then, the volcano has been in a quiescent state. Ischia is also quiescent, after its most recent eruption in 1302 (Iovine et al., 2017). Campi Flegrei last erupted in 1538 (Di Vito et al., 1987), but this wide caldera has been giving signs of unrest since the 1950s, with periods of remarkable seismicity and ground uplift in 1969–1972 and 1982–1984 (Del Gaudio et al., 2010). Then, after 20 years of continuous subsidence, a new and slower uplift phase began in 2005 and continues to the time of writing. Ground deformation is accompanied by minor and shallow seismicity and by changes in the composition of fumarolic gases. Observed changes led the civil protection authorities to shift the emergency level from green (background) to yellow (scientific attention on the phenomenon) in 2012 (Tamburello et al., 2019).

A dormancy lasting for centuries, followed by decades of unrest without eruption, is a common evolution for a caldera (Acocella et al., 2015). Unlike the case of stratovolcanoes, such as Vesuvius, even remarkable unrest phenomena may not constitute short-term precursors of an impending eruption. However, with more than 3 million people living in the municipality of Naples and a volcanic risk among the highest on the planet, this kind of volcanic pattern easily becomes a real communication nightmare. Living memories from the last eruption of Vesuvius further confuse the picture, bringing in vivid images from a very different volcanic setting.

Given the relevance of the problem, volcanic risk perception in the Neapolitan area was first tested in 2006, focusing on Vesuvius (Barberi et al., 2008). Results obtained for the Campi Flegrei caldera (Ricci et al., 2013) showed that volcanic hazards were not listed among the principal concerns of a community mostly worried about crime, pollution, and corruption. Nevertheless, the people participating in the survey did consider the likelihood of explosive eruption as being moderately high. At the same time, many failed to identify the hazards posed by the caldera, which was overshadowed by the concerns about Vesuvius. Researchers also highlighted the so-called optimistic bias, according to which responding citizens tended to consider themselves less prone to severe impact than their own town (Paton et al., 2008). In 2006, another study was carried out to test volcanic risk perception among 400 high school pupils (Carlino et al., 2008). Results confirmed a good knowledge of the volcanic risk among the pupils, although it was accompanied by a poorer understanding of volcanic processes and, at the time, also a lack of information about emergency planning. More recently, a wider study was carried out to address different kinds of hazards (hydrogeological, seismic, and volcanic; Avvisati et al., 2019). Results revealed the importance of direct experience of an eruption in assessing the likelihood of a future eruption and showed that a good knowledge of the hazard does not necessarily correspond to a good knowledge of best mitigation practices.

Within this context, we decided to focus on existing mental models of volcanic eruptions by forming a collaboration with the local schools (primary and junior high). The exploration of mental models usually takes the form of interviews (Skarlatidou et al., 2012) or face-to-face surveys accompanied by follow-up questions (Lacchia et al., 2020). However, considering our particular target, we opted for a different approach. To engage participants, we proposed a creative writing and drawing exercise, asking them to describe a short story featuring an eruption and its consequences. We collected approximately 200 stories that depict a range of rather plausible scenarios for this volcanic area. We analysed all the stories in detail, identifying the spatial and temporal frames in which kids place their eruption and the accompanying words and feelings.

While certainly not comparable to the results from more structured approaches, our exercise provided valuable insights on widespread expectations and useful hints for future outreach materials. The workshop proposed enabled us to discuss volcanoes and related hazards with the children, who are effective carriers of information for their families (Ronan and Johnston, 2005; Johnston et al., 2006).

2 The project

The imaginary eruption is an activity promoted within the EDURISK framework (https://www.edurisk.it/, last access: 11 July 2022), a long-term educational project with the aim of promoting educational itineraries for risk reduction for schools of all grades, with particular attention to ages 6 to 13 (Pessina and Camassi, 2012). Across this age range, pupils may learn about volcanoes and their activity; however, the information proposed may vary among different schools. The curriculum of the elementary schools (aged 6–10) does not specifically include Earth science, but geography lessons may focus on local landforms and their development. Earth science enters the curriculum only in the last year of junior high school (aged 11–13), when pupils gain a basic geological knowledge about rock formation, plate tectonics, earthquakes, and volcanic activity. Each school has the possibility to develop specific programmes to deepen the study of selected topics. Thanks to this flexibility, teachers working in volcanic areas may focus on volcanic activity and propose risk education programmes that vary in different school districts. Only very recently has information on natural hazards and on the functioning of the Italian Civil Protection entered the civic education school programmes.

The activity involved 10 school districts (8 in the Neapolitan area and 2 from non-volcanic regions) and was carried out during 2 school years in 2018 and 2019. A total of 25 classes participated in the activity, with 13 from primary schools (6–10 years old) and 12 from secondary schools (11–13 years old), for approximately 500 kids. In 2020, we proposed the same workshop to schools on the island of Stromboli. Due to the restrictions related to the COVID-19 pandemic, we held this activity remotely, via video conference. On Stromboli, we gathered 11 stories on the island, 9 of which were completed with drawings, and 2 featured only written text. Among the completed stories, 6 were from primary school and 3 were from secondary school. The analysis presented below focuses on the earlier workshops run face to face, while results obtained in Stromboli (i.e. remotely) are discussed as an aside. A list of the schools involved is provided in Table 1.

The imaginary eruption workshop was carried out within the framework of the EDURISK project proposed to all Italian schools. The schools' enrolment into the project is discussed by each school board, and once the project is approved, it is usually introduced into the school curriculum (Piano Triennale di Offerta Formativa) that is shared with the families every year. At the beginning of each school year, all schools require written consent from the families about the engagement of their child(ren) in the activities and projects proposed in the curriculum. The participation of each school into the project follows an official procedure that also ensures ethical clearance, considering that we did not collect any personal information about the participating pupils, pupils always worked in pairs or small groups, pupils were asked not to print their full names on their compositions, producing an outcome was not compulsory, and pupils were free to decide the degree of their involvement in the exercise.

The activity featured an initial phase of direct interaction with the attending pupils. During this workshop, we guided the stories' completion, as better specified below. We introduced the imaginary eruption as a creative exercise rather than a science essay. This was important to collect stories that probed the kids' mental model rather than reflecting lesson contents. We stressed the absence of a formal evaluation of the correctness of the description and suggested the possibility of fantastic settings or characters. At the end of the workshop, participants shared and discussed their stories. Each tale provided many opportunities to discuss eruptions, volcanic phenomena, various hazards, and their mitigation.

After the workshop with the pupils, we held three meetings with the teachers. During these encounters, we adopted participatory techniques and explored the thoughts and feelings that emerged from the collected stories. In a few cases, the teacher also participated in the same laboratory exercise as the kids, producing their own stories about the eruption. The meeting with the teachers explored different aspects of volcanic risk and resilience. During the first meeting, we addressed the environment and its relation to volcanic hazards and risks. The teachers explored the visible and invisible features characterising the landscapes where they live and work. The analysis provides clues about volcanic risks and what factors amplify or mitigate them. The second meeting focused on responsibility, community, resources, and problems. The group assessed how to prepare and what to do to mitigate the risk. Finally, the last meeting revolved around resilience and identifying the times and means to share information and understanding.

During the analysis, we used all of the considerations raised during these discussions to plan future outreach activities related to volcanic hazards.

3 The workshop

Pupils worked in pairs or small groups, and their assignment was to invent a story in four frames, each featuring both drawings and a written description. The materials required for the story's realisation included four sheets of paper (A4), pens, pencils, and colours, an eraser and sharpener, and scissors. We asked participants to cut the sheets into a square (21×21 cm) destined for the drawing and to use the remaining rectangular stripe for the written text. Once the material is ready, we provide instructions to start, and we specify the time (approximately 15 min) allowed for the completion of each frame. We instructed participants to complete one frame at a time, following simple instructions often offered in terms of guiding questions. An important detail is that pupils were unaware of their participation in a volcanic risk project and that the stories should have a volcanic eruption as their main theme. Instructions were as simple as possible to allow ample creative freedom but were needed to focus on volcanic eruptions and make the drawings comparable.

The first frame sets the story's scene. Pupils had to describe the main characters involved, the general setting, and the environment in which they move. We only gave the constraint that a volcano should be present. Guiding questions for this frame could include the following.

Our character(s) live(s) near a volcano:

  • What kind of place is it?

  • Who is the protagonist?

  • What are they doing?

  • How do they feel?

Only when the first frame was finished (or when the allotted time passed), did we provide information on the successive step.

In the second frame, something unusual happens with the volcano. Participants had to describe what was going on and the characters' reactions. The guiding questions enquired whether someone noticed the changes or took action.

  • The volcano is doing something unusual; perhaps it is waking up?

  • What does the volcano do?

  • Does the character see that?

  • Do they talk about it with someone?

  • Do they do something about it?

  • How do they feel about it?

The third frame focuses on the eruption. We asked participants to describe the volcanic event and describe its impact on the surroundings and how it affected the characters. Guiding questions included the following:

  • When the eruption begins, what does the protagonist do?

  • What do other people do?

  • What is happening around them?

  • How do they feel?

The fourth frame is the story's epilogue – the eruption is over. Participants described the new setting, where the protagonists are now, and how much time had passed since the eruption. Possible guiding questions were as follows:

  • The eruption is over: where are the characters now?

  • What do they do?

  • How do they feel?

An example of a full story is provided in the Supplement (Sect. S1; see “Whole stories”).

4 Results

We collected 188 stories completed with text and drawings (148 in colour) and two stories without written text. The stories often describe realistic settings, but many contain imaginary situations or magic characters and events. Stories take place in all sorts of locations, from the close neighbourhood to faraway, exotic places, as distant as other planets. Among the protagonists we find kids, youngsters, adults, superheroes, and animals. While stories tend to have a happy ending (in 163 cases), most of them acknowledge severe destruction caused by the volcano. Some stories (25) have a dramatic conclusion, and a few culminate with the protagonist's death. In the following, we first analyse the words used by the pupils to describe their stories. Then, we compare the stories that are narrated in the four frames.

4.1 The stories' language

We scanned all the stories and digitised the written descriptions (available for 188 stories) to perform a simple text analysis. All stories were analysed together as a unique dataset of words. Text mining was performed with the R software (R Core Team, 2020), using a specific package (tm) and involved a preliminary manipulation to remove the punctuation, extra white spaces, and the common words (or stop words), like articles or prepositions, which are not expected to bear specific information for the analysis. A collection of stop words is available for the Italian language in the R function we used (tm_map), but we added a few more that emerged from a first text review (as reported in the caption of Fig. 1). The resulting assemblage contained 3428 terms that were used with different frequencies. More than 1950 words were used only once. As expected, the most common term is vulcano (volcano), which is mentioned 581 times. Focusing on the other terms, the three most frequent words are casa (home), with 147 occurrences, Vesuvio (Vesuvius), mentioned 127 times, and lava, which appears 124 times. Figure 1 shows a histogram of the 20 most-used words (translated in the caption). A more general idea is provided by the word cloud.

Figure 1Frequencies of the most used terms in the written descriptions of the imaginary eruption and associated word cloud. The meaning of the terms are as follows: casa (home), Vesuvio (Mount Vesuvius), lava (lava), vicino (nearby), città (city), molto (much), due (two), giorno (day), eruzione (eruption), eruttare (to erupt), volta (time; turns), Luca, viveva (lived), fumo (smoke), ragazzo (boy), Napoli (Naples), anni (years), vede (s/he sees), subito (now), inizia (begins), fare (to do), and vide (s/he saw). Stop words added to the original list and not included in the count are: perché (why), così (therefore), poi (after), allora (then), cosa (what; thing), quindi (therefore), però (however), po' (a bit), dopo (after), mentre (meanwhile), lì (there), and quando (when).

The digitised text allows us to verify how many times specific words are used. We can see how many times death or survival are explicitly mentioned in the descriptions by searching for the recurrences of the words related to death (including the declination of the verb to die) and those related to survival or salvation. Frequencies of each term are listed in Table 2. The simple frequency of these terms does not reflect the actual meaning of the story, as it does not account for possible negation (e.g. “I did not die”, or “they did not survive”). Table 2 shows that terms referring to salvation are slightly more often mentioned than those referring to death.

The same exercise can show how many times the words girl(s) (ragazza) and boy(s) (ragazzo) are mentioned. The search included words for baby girls (bambina) and baby boys (bambino). The masculine term ragazzo (56) appears almost twice as often as the feminine ragazza (33). Baby boys and baby girls are mentioned less, but the difference between them is much smaller (bambino, 16; bambina, 14). The feminine plural terms are not common (ragazze, 7; bambine, 0), while the plural masculine, which in Italian may refer to both genders, is more frequent (ragazzi, 34; bambini, 15). These kids and youngsters are often protagonists of the stories and are commonly surrounded by their friends and family or by other people. Sometimes, the pupils themselves are the protagonists in their own stories. Figure 2 illustrates the frequencies of the terms related to the people who are protagonists of the stories (specific Italian terms are listed in the figure caption).

Figure 2Frequency of words related to friends, families, and communities. The categories shown in the figure include the following Italian terms: community – cittadini (citizens), abitanti (residents), persone, and gente (people); friends – amico (friend) and compagno (companion); parents – mamma (mum), madre (mother), papà (dad), and padre (father); family – famiglia (family); siblings – fratello (brother) and sorella (sister); grandparents – nonna (grandma) and nonno (grandpa; note that the Italian language does not have a formal expression for grandmother or grandfather); and aunts and uncles – zia (aunt) and zio (uncle). Both singular and plural and masculine and feminine terms are always counted.

The written descriptions shed light on the words used to describe the volcanic phenomena and products. The imaginary volcanoes mostly emit lava (124) and smoke (57; Fig. 3), but products of magma fragmentation are also described as ash (19), stones (18), and lapilli (11). Magma, volcanic gases, and dust are also mentioned a few times.

Other words that may be of interest in this analysis are those referring to professional figures that may be related to the assessment and the management of volcanic crises. Terms associated with these professional roles include scientists (16; 1 of which is female), volcanologists (17; 1 of which is female), geologists (8; 4 of which are female), firefighters (12), civil protection, police, rescuers, and the mayor (2). The corresponding Italian terms are as follows: volcanologist – vulcanologo; scientist – scienziato; geologist – geologo; firefighters – pompieri and vigili del fuoco; civil protection – protezione civile; police – polizia; rescuers – soccorsi; and mayor – sindaco. Both singular and plural and masculine and feminine terms are always counted.

Words can also tell us something about how the characters feel about the events. Figure 4 shows the most common words related to sentiments. Fear (79) includes terms such as paura (fear; 31), panico (panic; 10), impaurito/a (scared), and various forms of the verb spaventare (to be scared). The term happiness (22) includes words like felice (happy; 26), contento (glad; 20), or felicità (happiness; 1).

Figure 4Frequencies of terms related to sentiments like fear, happiness, concern, sadness, and curiosity. The corresponding Italian terms are as follows: fear – paura (fear), panico (panic), impaurito (frightened), spaventato (scared), and spaventare (to scare); happiness – felice (happy), contento (glad), and gioia (joy); concern – preoccupato (worried) and preoccupazione (concern); sadness – tristezza; curiosity – curioso (curious) and incuriosito (intrigued). Both singular and plural and masculine and feminine terms are always counted. In the case of verbs, different tenses and persons are considered.

4.2 The frame contents

In the following, the collected stories are compared, frame by frame, with respect to their content. The following analysis takes into account both the written text and the drawings and focuses on the plot of the collected stories, with particular attention on the description of natural phenomena and human response.

4.2.1 Frame 1 – the protagonists and the environment

In 148 stories (78 % of the total), the main characters are real people, often representing the authors themselves or other kids slightly older than them. In 43 % of the stories, the protagonists are referred to as boys (55 times) or girls (27 times), but in many stories adults (one or more) are present. Adults are mostly men (77 % of adults) and are often identified through their employment (e.g. farmer, scientist, explorer, rock star, hunter, lumberjack, astronaut, or soccer player). Scientists are mentioned as leading characters in 12 stories, including 4 times as volcanologists and 2 times as geologists. In two stories, the protagonists are related to civil protection. In a smaller number of cases, the adults are identified through their family relations with other characters (grandpa, husband, wife, mother, or father). Often the protagonists are accompanied by friends or pets, and in a few stories, the animals are the leading characters. Fantasy characters appear in 54 stories and include princes and princesses, magicians and fairies, cartoon characters and superheroes, aliens, gods, and pirates. In a few cases, the volcano itself becomes a character, with anthropomorphic features.

The volcano is always represented as a conic mountain and is generally rather small. Sometimes it is depicted with two peaks, mimicking the profile of Mount Vesuvius surrounded by Mount Somma, the remnant of an ancient caldera structure (interestingly, Mount Somma is often represented as a second volcano with its own crater). Only one story features a submarine volcano. The volcano can be a real one, with Vesuvius being the most common choice (named in 32 stories), followed by Etna (13) and Solfatara (2). Stromboli, Vulcano, Ischia, and Monte Nuovo are also mentioned once each. In a few cases, the volcano has a fantasy name, while often it is nameless. Explicit reference to the city of Naples is also present in 17 stories. Other localities mentioned include Sicily (8), Pompeii (4), Ercolano (3), and Torre del Greco (2). Exotic settings are also frequent, with reference to Hawaii (4 stories), Arequipa (Peru), Australia, Hollywood, Los Angeles, Paris, Alaska, Russia, Texas, Norway, or the Caribbean. The volcano can be on an island (18 stories) or surrounded by woods (8) or in the countryside (9). Exotic environments include the savanna, the Indian jungle, or the desert. In total, four stories are set on other planets.

Inhabited areas are rare and are often represented by a single house (17 stories) usually built near the volcano. In a few cases, there is specific mention of a small town or a village nearby (13 times) and only seven stories mention a city.

A few examples of the first frame are collected in the Supplement (Sect. S2; see “Frame 1 – the story's settings”).

4.2.2 Frame 2 – something happens

The most frequent sign of volcanic unrest is the ground shaking (in 48 stories), sometimes described in terms of seismicity (the word earthquake is used 12 times, with a couple of references to its magnitude). Other stories use generic terms like tremor (20 times) or ground movements (15 times). Opening of cracks, landslides, or building collapse are also mentioned (Fig. 5). Another common signal of volcanic unrest is the presence of smoke on top of the crater, which is mentioned 44 times in this frame. Based on both the written description and the drawings, the word smoke is used to intend volcanic gases (which are explicitly mentioned only two times). Another reference to degassing activity is the smell (sometimes specifically a sulfur smell), that is mentioned in eight stories. Volcanoes also make noises, which are mentioned in 33 stories. Other signs of unusual behaviour refer to actual eruptive processes, like the emission of lava (20), or various ejecta (stones and rocks, lapilli, and volcanic ash, mentioned in 14 stories).

Eruptions or explosions are mentioned 47 times at this stage of the story. In a few cases, the signals that something is going on are changes in the volcano's colour or appearance, or the characters perceive an anomalous heat. Flames and burned vegetation are mentioned in a few cases, while animals detect the unrest in a couple of stories. In most cases, evidence of volcanic unrest is obvious enough for the protagonists to notice it themselves. The only (indirect) reference to sensors installed to monitor the volcano is a seismogram drawn in one of the stories, while another three mention the magnitude of the earthquake, which presupposes the presence of seismometers in the area. In all other stories (the vast majority) the signals from the volcano are easily detected by residents, with no need for monitoring instruments. Sometimes the characters learn (or have confirmation) that something is going on by watching the television (eight stories).

Most characters are frightened by the unrest (39 stories mention fear in this frame). Common reactions include talking to other people (50 % of the stories) to warn them but also to ask for explanations or seek help. In about 30 % of the stories, the protagonists have a companion, and sometimes they may talk to each other about what is going on. Talking to other people involves friends (26 stories), family (22), scientists (12), the community (either everybody or the neighbours; 10). The authorities (police, firefighters, civil protection, but also the mayor, the professor, the director, etc.) are called upon in nine stories, while in five instances the protagonists refer to a wise, old character for advice.

In a few stories, the protagonists try to warn others but are not believed or receive no answer. In one story, the volcano itself talks to the protagonist and warns the protagonist to go away. In another story the warning comes from the mail carrier. In most cases, the protagonists realise that an eruption is possible, sometimes thanks to the opinion of others. Only in a few cases do the characters fail to recognise the danger or consider the signals a normal feature or behaviour of the volcano, thus not worth any cause for concern.

In the majority of the stories, this frame does not specify whether the characters are going to take action. Only 22 stories (12 % of the total) explicitly refer to leaving the place because of the impending danger, while in 15 cases, the character goes or remains home or seeks shelter, waiting for further development. While most of the protagonists are worried, some are fascinated by the unusual phenomena or look for answers and willingly move toward the volcano (17 stories). In a few stories (12), the characters seek a remediation for the problem. Sometimes it is a magical intervention, while others refer to some kind of authority to fix the problem (usually in an unspecified way). A small number of protagonists take action to mitigate the hazard, obstructing the volcanic vent with rocks (or even a cork) or pouring water inside the crater.

Examples of frame 2 are provided in the Supplement (Sect. S3; see “Frame 2 – volcanic unrest”).

4.2.3 Frame 3 – the eruption

The eruption is usually sudden. The terms improvviso (sudden) and improvvisamente (suddenly) are used 26 times in this frame and subito (immediately) appears 8 times. The event may be described as an explosion or a blast (32 times). Based on drawings, it is usually a small-scale event, whose impact is generally confined to the upper portion of the volcanic cone. It commonly involves the emission of lava (mentioned in the text 60 times), but the Strombolian ejecta are present in several drawings. Written text mentions ash, rocks, and lapilli (23 in total for this frame). Flames are also mentioned about 10 times, as a result of fires set by the incandescent eruptive material. Only a few stories actually depict a major explosive eruption that occupies most of the drawing area and generate clouds of ash that could represent pyroclastic flows. The terms pyroclastic flow, or nuée ardente, are never used in the written descriptions.

As the volcano erupts, people scream and run away but also watch, in a few cases with fascination, while many are frozen in fear. Many characters just watch, gathering in the streets but without leaving. In several stories, the onset of the eruption is the time when the characters begin to worry and start wondering what to do next. In a few cases, this is the frame where people are warned about the danger, often by word of mouth, and only in very few cases through official actions (a siren or police or civil protection authorities alerting the population). The word evacuation is only mentioned twice.

The most common reaction to the eruption is to flee (83 times in this frame, i.e. 60 % of the stories considering both text and drawings), mostly by running (Fig. 6).

Many escape on a boat or a raft (20), while others rely on their cars. Airborne vehicles are also popular, particularly helicopters, but also aeroplanes, air balloons, or fantastic vehicles. Only a few leave the town by train or bus or use animals. Many seek shelter, often returning to their home (26 times) or entering into the sea. Also in this frame, a few bravely take some sort of action to mitigate the hazard (34 times), either through magic intervention or also by pouring water into the crater or by throwing rocks into the volcano to obstruct the conduit. Rarely is the action taken by the community or by public authorities.

Others call for help (21 times), sometimes hopelessly.

Text and drawings also reflect the damage (mentioned 34 times) to the environment (burnt vegetation) and to infrastructures (houses, mostly, but also cracks or lava interrupting roads). In 9 % of the stories, the destruction is pervasive and impacts the entire city. In 11 stories, someone dies in this frame, and in a few cases the protagonists themselves do not survive. Examples of the third frame are collected in the Supplement (Sect. S4; see “Frame 3 – the eruption”).

4.2.4 Frame 4 – the epilogue

This frame shows how things ended, and the participants imagined a rather wide spectrum of possible outcomes. In some stories the old life resumes, as if nothing happened, thanks to magic interventions or because it turns out it was just a dream. In other cases, nothing will be the same ever again because someone died or because it was necessary to move and live elsewhere. Most of the stories end well (58 %), and the characters survive, perhaps a little battered (bruises or wounds are mentioned; in one story the two characters end up with a headache). They often contribute to save their community and happily celebrate the end of the eruption. The relief is usually burdened by the damage caused by the volcano. Even though the characters are alive, in several stories (28 %) they face destruction and losses. Destruction is mentioned 38 times in this frame, and it affects both the environment (trees and animals) and urban infrastructure (buildings and roads) that are burnt (15 stories) or covered in ash (11 stories).

The disconsolate assessment of the devastation may be accompanied by the idea of reconstruction (13 % of the stories), which may take place either right away or after a long time. The protagonists may or may not be directly involved. Some choose to rebuild elsewhere. Sometimes, the reconstruction is carried out while the characters are away, in a safe place. Other times (11 %), the reconstruction is described as a community effort acted by everybody, by the city, or by the inhabitants. Only in a few cases (3 %) are specific categories mentioned to be in charge of reconstruction (masons and firefighters). Sometimes the community that builds a new life after the disaster is limited to the characters and friends or relatives. Rescue teams of some sort are mentioned only six times in this frame.

The need to move away is again mentioned (24 % of stories), and only some of the protagonists (7 %) envisage returning home, perhaps after a long time. A small number of stories (10 %) do not end well, and remind us that things can go badly. Death is explicitly mentioned 38 times in this frame, and in 15 stories, the protagonists themselves die, sometimes in a heroic effort to save their community and other times in loneliness or because nobody survives. In a couple of cases, the death is not directly related to the eruption but is due to indirect or independent causes (heart attack, being hit by a firefighters' truck, and even by an atomic bomb, which is totally unrelated to the story).

A few stories do not provide details on the epilogue and simply state that the eruption ended, without further comment. The story simply ends because the volcano turns off (or it rains, and this stops the eruption). There may be an acknowledgement that everything is burnt but without information on what happens to the characters. In one story, the houses are only covered by ash but are still habitable. In another one, the bad ending features widespread destruction and scientists who do not know what to do.

Examples of the fourth frame are collected in the Supplement (Sect. S5; see “Frame 4 – the epilogue”).

4.3 Stromboli

The same workshop was later proposed to the pupils living on the island of Stromboli (Aeolian Island, north of the coast of Sicily). This offered us the opportunity to collect stories from a context that is very different in terms of its geographic, volcanic, and social settings. Stromboli is an open-conduit volcano, usually characterised by a mild Strombolian activity (which takes its name from the island itself) and features continuous degassing and repeated explosions ejecting materials up to tens or hundreds metres above the crater. Lava flows may occasionally form along the deserted slope of the volcano. This persistent activity typically impacts only the summit of the volcano and is considered one of the main touristic attractions on the island. This behaviour is sporadically interrupted by greater explosive events, known as paroxysms. The imaginary eruption workshop was carried out in 2020, right after two paroxysmal eruptions took place in 2019, on 3 July and 28 August (Giordano and De Astis, 2021). Both events raised an eruptive column of several kilometres and generated pyroclastic flows that rushed down the deserted slope of the island to reach the sea. The two paroxysmal eruptions occurred without noticeable precursors, were unusually close in time, and the first one caused one causality, shaking the busy touristic season that revolves around guided tours of the volcano's summit. Residents had to face the fear of both volcanic eruption and economic disruption at the same time. In this context, we planned a workshop for spring 2020 but, because of the COVID-19 pandemic, we could not travel to the island. We did not want to miss the opportunity to be in touch with the pupils and to offer them a safe space to discuss volcanic eruptions and their consequences. We therefore adapted the workshop to make it suitable for an online platform. Participants connected from their homes, and since it was not possible to organise the work in pairs, each pupil elaborated their own story. We allowed longer times to work and to discuss the stories at the end. The workshop was therefore organised in 3 d, with one session of 1 h each day. The attending pupils were 13, from both primary and secondary schools, but we could collect only nine stories featuring both drawing and written descriptions. This is a very small number to allow for wide consideration. Nevertheless, we do consider these stories of interest for the peculiar circumstances they reflect, and we therefore provide here a brief description. Most stories are set on the island itself which, in two cases, is the actual protagonist. The impending eruption can be announced by rock fallout (which, in one case, set the vegetation on fire), small tremors, or even small eruptions. In one case, the eruption is announced by an air pocket. The eruption is often a typical strombolian eruption, with a lively launch of ash and scoriae, sometimes associated with a lava flow. In one case, the eruption begins underwater, while in another one pyroclastic flows and their destructive power are mentioned. The stories mostly feature a happy ending, with the volcano returning to its usual behaviour, and inhabitants can resume their usual lives. In a few cases, however, consequences are more serious and involve injured people or imply leaving the island and friends.

5 Discussion

The imaginary eruption provides a composite portrait of volcanic eruptions and their impact, as perceived by the kids and youngsters, mostly from the urban area of Napoli. As a whole, it is a rather accurate portrait featuring many realistic features that can be expected during a volcanic event. Collected stories provide a wide range of plausible eruptive scenarios. A comparison with those envisaged by the scientific community reveals a few gaps and discrepancies that could inform future outreach programmes.

5.1 The volcano and its activity

In all collected stories, the volcano is an obvious geological feature of the landscape, and the eruption invariably takes place at the summit of the cone. A caldera setting is never mentioned, nor the possibility of new vents opening along the slope of the volcano, or elsewhere. Pupils are commonly very passionate about volcanoes, and this passion is generally accompanied by a good knowledge of different volcanic structures and phenomena. While many of the kids involved are certainly aware of calderas and their behaviour, the choice of representing classic volcanic cones reflects the conventional image that we all picture when we think about volcanoes. Some drawings explicitly refer to Vesuvius and realistically feature two peaks, with one representing Vesuvius' cone and the other being the remnants of the Somma stratovolcano. These drawings are testimonials of the interest and good knowledge of the local landscape. In most stories, however, the imaginary volcano is located in remote regions, surrounded perhaps by a few isolated houses and, in general, at safe distance from populated areas. Only in a few cases is the volcano portrayed in an urban environment.

Volcanic unrest is marked by a number of realistic precursors, such as shallow seismicity or the emission of smelly volcanic gases, and is often associated with noise. Interestingly, in some cases, the first signs of volcanic unrest are actual eruptive events, involving explosions and the launch of ejecta. In general, the unrest phase is too short to take action before the volcano erupts. The quick transition from unrest to eruption suggests that most stories feature volcanoes with an open conduit. Open-conduit volcanoes erupt more frequently, and their activity is more likely to appear on television or social media. These images easily contribute to the building of our mental model of erupting volcanoes. The eruptions from open-conduit volcanoes are easily strombolian, featuring launches of volcanic bombs, lava flows, and spectacular lava fountains that closely resemble the events drawn by the kids.

Most imaginary eruptions are small events, if seen through the eyes of a volcanologist. The main feature is usually a lava flow that propagates along the slope of the volcanic cone. This effusion is commonly accompanied by the emission of gas and by the launch of lapilli and bombs that, in a few cases, may reach beyond the volcano's slopes. This eruptive style recalls common footage from frequently active Etna or Stromboli volcanoes in Italy. Some stories mention ash, and this may reflect family anecdotal accounts of Vesuvius' last eruption in 1944. A small number of drawings show the development of an eruptive column (that is never mentioned in the written text). The height of the column is usually small compared to the size of the volcanic edifice. Only in a few cases does the drawing suggest that the eruption impacted a wider area (i.e. the entire city). Most stories provide little or no evidence to assess the duration of the eruption. When they do, the event is short-lived and usually ends within a few hours or a day.

The imaginary eruption has consequences. Most stories describe burnt vegetation and damage to houses and roads. In some stories, people are hurt or killed. Almost half of the stories (42 %) mention casualties, but most stories reflect the optimistic bias already seen in the analysis of risk perception conducted among adults. In these cases, the protagonists survive even though others are severely affected. Ash covering the landscape and causing respiratory problems is also mentioned a few times. Damage may be limited (especially when the eruption itself is small), but in a few stories, destruction is pervasive. In many cases, the eruption's consequences are long-lasting and affect the lifestyle of the characters involved.

Interestingly, in a few stories the characters are killed or injured by events that have nothing to do with the eruption, suggesting a clear understanding of the multiple hazards that threaten our communities.

The stories collected in Stromboli reveal a strong relation with the volcano and a good knowledge of its various eruptive styles and products. The two stories that feature the volcano itself as a protagonist both suggest a strong tie connecting Stromboli with its islet Strombolicchio and with the other Aeolian islands. This is consistent with the geological evolution of the archipelago. In general, both the drawings and the written descriptions of the stories reveal a close attention toward eruptive phenomena and their consequences.

As mentioned in Sect. 2, some of the stories (39) were collected in schools located in non-volcanic areas. We did not perform a systematic comparison of stories drawn in different regions, but we can say that those collected in non-volcanic areas often lack detail in the drawings and descriptions of volcanic activity, both before and during the eruption. The presence of suspended ash, which can cause coughing and hinder respiration, is only mentioned in stories collected in the Neapolitan area and may reflect familial accounts of the 1944 Vesuvius eruption.

5.2 The people

The characters who live or find themselves near the volcano are commonly alone or with a single companion. In most cases, they face the unrest and the eruption without the support of a wider community. The protagonists are mostly well aware of the impending danger and discuss their options and fears with friends or neighbours. The stories provide a very realistic picture of people's behaviour, highlighting well-known issues, such as warning signs or alerts that are met with disbelief and lack of action. The stories also capture both the fascination and the fear of the natural phenomenon as being major drivers for people's actions. While most run or seek shelter, some are paralysed by fear, and a few reckless characters are attracted to rather than scared by the volcanic activity. The struggle to decide whether or not to leave is also present. The need to move somewhere else to be safe is a recurrent concept, likely reflecting some knowledge of the emergency plans for the Neapolitan area. However, leaving is always depicted as a personal decision that not everybody is willing to make.

Moving away from the volcano as a safety measure is described with different nuances in different geographic areas. Kids living far away from actual volcanoes may describe the departure with relief, as a permanent solution to the problem with no apparent drawbacks; kids from the Neapolitan area, on the other hand, seem to be sorely aware of the many difficulties associated with leaving and often describe the characters as sad, lonely, and homesick.

A good perception of the complexity of life on an active volcanic system also emerges in a couple of stories from Stromboli, where people's concerns are mentioned in addition to the necessity to leave to be safer elsewhere. One story addresses the very different perceptions that different people may have of the same phenomenon, ranging from admiration to fear.

In general, the departure is not a planned evacuation, organised and carried out before the eruption, but rather an escape from the ongoing phenomenon. In several cases, it takes place after the eruption ended, not as a defensive measure but because houses are damaged, as it happens in case of earthquakes. In the (rare) description of rescue teams, they also intervene in the aftermath of the eruption. In a seismic country like Italy, images of rescue teams at work after major seismic events is unfortunately a rather common sight that has easily entered the mental model of the kids.

An organised approach to hazard assessment and mitigation is missing. There are neither monitoring networks to capture signals nor experts capable of interpreting them. If scientists are at the scene, they mostly acknowledge the ongoing activity, without providing further information or useful advice. Public authorities are rarely mentioned (less than 5 % of the stories), and there is no coordinated, public response to the change in the volcano's state of activity. Most of the characters face the impending danger on their own, and if action is taken to lower the risk, it mostly happens thanks to individual initiative.

In a small fraction of stories (approximately 10 %), the aftermath of the eruption is characterised by reconstruction that sees a full involvement of the entire community.

6 Conclusions and steps forward

The kids and youngsters attending the imaginary eruption workshop revealed sharp eyes and a keen attention to the dynamics of both the natural phenomena and human interactions. Their work, considered together as a whole, captures most of the key issues related to hazard assessment and mitigation. These were discussed at length in the meetings with the teachers after working with the pupils.

The outcome of an eruption does not only depend on the magnitude and explosivity of the volcanic event; people also play an important role. The conclusion of the story always depends on what goes on in the preceding frames. The kids' drawings represent the wide spectrum of possible combinations of eruptive styles and sizes and people's behaviours well.

The collected stories are works of fiction, and do not necessarily represent the actual beliefs or mental model of the drawers. Nevertheless, in setting up the scene, the pupils made use of their personal knowledge, and the stories reveal what they think could cause their protagonists to be in trouble. The analysis of individual stories can be used to identify sound elements of their understanding of volcanic eruptions and point at topics that may deserve further attention in future outreach work. In the future, scientists and textbook writers should become acquainted and agree on the choice of images and terms to better convey a more realistic picture of volcanoes and their behaviour. Graphics could illustrate possible sequences of events before, during, and after the eruption, together with the timescales and magnitudes involved. In the following, we provide a few indications.

  1. Unrest and uncertainty. Among the positive elements, kids are aware that there will be precursors to an eruption in the Neapolitan area and can name several of them. On the other hand, the stories typically describe a very short unrest phase, with macroscopic signals that are detected shortly before the actual onset of the eruption. The stories do not capture the uncertainty associated with long-lasting unrest periods, featuring signals whose interpretation may be difficult or controversial. This crucial phase requires a continuous effort to find an acceptable balance between costs and benefits of possible mitigation actions, causing great stress in the resident population. Yet, the description of the unrest phase is easily neglected in the concise descriptions that classifies volcanoes as dormant or active. New outreach materials could focus on what it takes, and how long it takes, to actually reactivate a dormant volcano. Dealing with uncertainty is hard on emergency managers and citizens. Being aware that a period of uncertainty is ahead of us is a first step to prepare for it and possibly take action to mitigate the fatigue associated with it.

  2. False alarms. Some volcanic unrests terminate without culminating in an actual eruption. This has occurred at Campi Flegrei several times (Del Gaudio et al., 2010) and has important implications for hazard assessment; if an eruption is not the only possible outcome of precursory signals, then false alarms based on monitoring signals are bound to happen. This possibility is never mentioned in the collected stories and should be perhaps better emphasised when discussing volcanic hazards.

  3. The magnitude of eruptions. When the imaginary eruption strikes, it is usually small. The drawings may in part reflect images and sketches that pupils find in their books, where the various features of explosive eruptions are concentrated in a small space due to publishing constraints. We may collaborate with graphic designers to devise sketches of volcanic eruptions that provide a better understanding of the actual size of big explosive events. And we can highlight that the same volcano can display very different eruptive styles and generate big and small events.

  4. Time for action. The frame describing the eruption is also the one when most protagonists decide to take action. The kids expect that an eruption will have a great impact and know that it will be necessary to run or seek shelter. Outreach material and education itineraries should emphasise that there is time for evacuation, and this time is before the actual eruption begins. Although distressing, a prolonged unrest phase is just what grants us enough time to organise an orderly evacuation.

  5. Planning ahead with families. As mentioned above, the characters of the imaginary eruption do not evacuate but try to escape, while others hide inside huts or other improbable shelters. The decision is never planned ahead but is made in the heat of the moment. In making these decisions, the characters of the stories mostly rely on their families. In reality, plans for an organised evacuation exist for exposed areas (red and yellow zones), as detailed in the National Civil Protection Plans for Vesuvius and Campi Flegrei. However, in a social context where family ties are strong, outreach activities should take into account that important decisions will be made within the family unit. Education efforts should target all family members, helping the kids to identify unsafe behaviour and the adults to recognise their optimistic bias. Outreach activities that target the entire family could significantly improve the preparedness of the communities.

  6. Taking responsibility. A small but significant number of stories describe efforts to stop the eruption from happening. While we certainly cannot control volcanic activity, there are common actions that are taken to hinder lava flow propagation, either by using cold water or building dams to temporarily contain or divert the lava. The problem-solving attitude should be encouraged by showing the kids that their thinking was very much consistent with existing mitigation strategies. Kids are willing to take responsibility and act to mitigate the hazard. We must emphasise that, in case of large explosive eruptions, evacuation is the only viable option.

  7. Science and scientists. In a few cases, the characters refer to scientists for help, but the nature of the support provided is somewhat blurred. We can work to better emphasise the insights we gain from volcano monitoring and from experience gathered at different volcanoes. This knowledge provides the information based on which mitigation actions such as evacuation can be taken. Volcanic gases are recognised as an integral part of the volcanic activity, but gas is commonly confused with smoke. Specific outreach material should stress the differences between volcanic gas and smoke and provide information on the key role of gases in hazard assessment. Finally, a few stories reveal the fear that scientists or authorities will not listen. We need to reinforce the bond between scientists, emergency managers, and the population exposed to volcanic hazards. All the initiatives such as science fairs, citizen science programmes, evacuation exercises, or community meetings bring these stakeholders together and contribute to building and reinforcing mutual trust and understanding.

The imaginary eruption has been an interesting exercise that has provided us with an unusual insight into how volcanic eruptions are perceived by kids and youngsters. Far from being a formal assessment of the pupils' understanding of volcanology, these stories provided valuable cues to discuss volcanic activities with the kids and explore a wide range of emotions and sentiments stirred by the thought of an impending eruption. The teachers involved mostly found this an effective tool to approaching a complex topic and to building lectures around the themes that the pupils propose in their stories.

This approach can be easily implemented to explore the mental model related to different natural hazards. We proposed the imaginary earthquake workshops to schools of various Italian regions to address seismic risk. During the EDURISK activities (Camassi et al., 2021), we learnt to constantly adapt our approaches and procedures during the projects in the schools, and when the COVID-19-induced restrictions caused us to adapt our teaching activities to the new constraints, we experienced closer and more immediate contact with pupils and teachers. The tools we used in person have been adapted to online, remote teaching. The activity was structured in the same way, through a four sheets of paper story that was drawn and written, and we managed to keep the same style of active participation that was built on stimuli and discussions. The results we have obtained, in terms of pupils' laboratory restitutions, are fully comparable with those described above, as obtained from the pupils of the Neapolitan area. We believe that this approach could be further extended to other natural hazards.

Short summary
How do kids imagine the onset and outcome of a volcanic eruption? A workshop proposed for schools tries to answer this question by collecting stories and drawings done by kids (aged 6–13). The eruption they have in mind is an excellent starting point for building classroom conversations about volcanic risk and its mitigation. Concurrently, the workshop provided us with valuable hints to improve educational materials and lesson plans to account for kids’ knowledge and beliefs.
