[MIS11-P05] The cooperative research with Tokachidake Geopark and Hokkaido University of Education at Asahikawa: Development of educational materials for the dynamics of pyroclastic flows

Tokachidake Geopark mainly work on education and conservation activities. Promoting educational activities while protecting and maintaining local resources is important for children, who will be responsible for the future, to take an interest in the local environment and to promote disaster prevention. In addition, we hope that it would be even better if as many children as possible could notice the interest of "Earth Science" through this works.
Tokachidake Geopark consists of two towns, Biei and Kamifurano. At elementary schools in Biei Town, 3rd to 5th graders are given time to learn about the local area as part of their classes as "hometown learning." Even at elementary schools in Kamifurano, by actively incorporating Geopark visiting lectures and Tokachidake excursions into their classes, they have more opportunities to consider about what is the normally and/or specialty in the town they live in. In the Tokachidake Geopark area, periglacial landforms based on pyroclastic flows called wavy hills are prominent. This large-scale pyroclastic flows consists of Tokachi pyroclastic flows and Biei pyroclastic flows, but no one has ever witnessed the “phenomenon” because it occurred about 2-0.8 million years ago.
Therefore, we are working together with Hokkaido University of Education at Asahikawa, associate professor Eiichi Sato, and the students of his laboratory to development of teaching materials for pyroclastic flow experiments that can be used not only for visiting lectures at elementary schools, but also for some educational and promotional events. For the first step, we have created a volcanic edifice modeled on Mt. Tokachidake and for the second step, we have searched for the most suitable condition setting to maintain an eruption column in the water. Subsequently, that eruption column collapses to lead to the generation of pyroclastic flows. We report the results here.
