Mount Unzen
Mount Unzen (雲仙岳, Unzen-dake) is an active stratovolcano of several overlapping small, volcanic cones, near the city of Shimabara, Nagasaki on the island of Kyushu, Japan's southernmost main island. In 1792, the collapse of one of its several lava domes triggered a megatsunami that killed 14,524 people in Japan's worst volcanic-related disaster.
