Overview: A variety of volcanic processes shape landscapes. Students are introduced to volcanic hazards that may be present for humans near the volcano. A volcano does not have to be active in order for some types of hazards to occur. Volcanic hazards can be categorized into gases, lahars, landslides, lava flows, tsunamis, pyroclastic flows and tephra. Many different volcanic hazards endanger the lives of Japanese and American citizens. After students are able to identify the volcanic processes they then identify which pose hazards locally. Students will prepare a brochure to educate the public on hazards of their local mountain and how to mitigate danger.
