[HDS09-P09] Preliminary survey on the awareness of volcano disaster prevention at Mt. Ontakesan among university students in areas without active volcanoes
Keywords:Volcano Disaster Management, Disaster Prevention Literacy, Science Education, Mt. Ontakesan
Mt. Ontakesan erupted on September 27, 2014, claiming 63 lives (including missing). The casualties were limited to climbers near the crater (1). Since then, the necessity of volcanic disaster prevention has been discussed not only for residents around volcanoes but also for tourists and climbers. In general, volcano eruptions occur less frequently than other natural disasters and the damage is limited locally. Residents in areas without nearby active volcanoes rarely consider volcanic disaster prevention, but they can suffer when visiting volcanic regions as tourists or climbers. Aichi Prefecture has no active volcanoes, but many climbers from Aichi were affected at the 2014 eruption of Mt. Ontakesan. Questionary Surveys for climbers at Mt. Ontakesan conducted after the eruption indicated a high proportion of climbers from Aichi Prefecture (2).
In this presentation, we will report about a preliminary survey conducted on university students in Aichi Prefecture regarding their awareness of volcanic disaster prevention and recognition of volcanic phenomena terminology. The subjects are first- to fourth-grade students taking classes related to Earth Sciences as their liberal arts curriculum at Chubu University. The survey was conducted anonymously using Google Forms. There were 49 responses, approximately 10% of the participants. Questions regarding the respondents' attributes included gender, home prefecture, and department. Among the respondents, 73% were from Aichi Prefecture, followed by 12% from Gifu Prefecture.
The questions about Mt. Ontakesan included awareness of the 2014 eruption, Ontakesan Volcano Laboratory, Nagoya University (3), Ontakesan Volcano Meister system (4) and two Ontakesan Visitor centers (Sato Terrace Mitake, Kiso town and Yama Terrace Otaki, Otaki Village) established after the eruption. It also includes questions about visits to the area for purposes other than climbing and summiting after the eruption.
Awareness of the 2014 eruption was relatively high, with 89.8% of respondents indicating they were "well aware," "somewhat aware," or "have heard of it." Regarding the damage situation, 67.3% recognized that climbers near the crater were casualties. On the other hand, awareness of the Volcano Laboratory, the Meister system, and the visitor centers was low, with "not knowing or never heard of it" accounting for 83.7%, 87.8%, and 79.6%, respectively. Additionally, no respondents reported climbing to the summit of Mt. Ontakesan after the eruption. Regarding visits to the Ontakesan area for purposes other than climbing, 79.6% answered "don't know or have never been."
To compare with surveys for other regions, we asked awareness of volcanic phenomena such as lava flows and volcanic ash etc. While awareness of lava flows (91.8%), volcanic lappli and block (100%), volcanic ash (99%), volcanic gases (97%), and pyroclastic flows (87.8%) was relatively high, awareness of snowmelt-type volcanic mudflows (22.4%), volcanic debris flows after eruption (53.1%), landslides and rock avalanches (57.1%), and air shocks (26.5%) was low. It was found that despite not visiting the Ontakesan area very often, respondents had high awareness of the 2014 eruption. In the future, we would like to consider the survey items, increase the sample size, and conduct cross-statistics, qualitative analysis of free descriptions, and detailed comparisons with other regions.
