Volcanic Hazards - Japan Most of active volcanoes in Japan
formed stratovolcanoes or complex volcano. These volcanoes
potentially produce the volcanic hazards such as pyloclastic
flows, laha, volcanic bombs, ash falls potentially that travel
faster and longer distances. Because Japan volcanic-arc is
linked to the Cascade Volcanic-arc by the Ring of Fire, the
volcanic hazrds in Japan are very similar to the hazards in the
Cascade volcanoes, for example Mt. St. Helens eruption in1980
(1). Some of those volcanoes are located near highly populated
areas. People in areas often face to the serious volcanic
hazards when the volcanoes erupt, for example Unzen and Sakura-
jima volcanoes. Map of major volcanoes in Japan (USGS) (1) R S
