Unzen

The massive Unzen volcanic complex comprises much of the Shimabara Peninsula east of Nagasaki. Unzen is well know for Japan's greatest volcanic disaster. In 1792, about a month after lava stopped erupting from the volcano, a landslide from nearby Mount Mayuyama swept through ancient Shimabara City, entered the sea, and generated a tsunami that struck nearby areas. More than 15,000 people were killed by the landslide and tsunami. Now the area is a national park. Many hells and volcanic activity led to the creation of a number of onsens.






On June 3, 1991, this dome collapsed and the explosion produced a pyroclastic flow and ash-cloud surge that raced 4.5 kilometers from the crater, burning about 180 houses and killing 43 people who had ventured into a previously designated hazard zone. Subsequently, lava continued to extrude from the summit crater toward the volcano's east flank. Another collapse event on June 8 swept 5.5 kilometers down the same river valley, burning 210 additional houses. Notice the lack of trees on the mountain.
