The agricultural area on floor of an explosion crater (left) and a flat-topped lava dome (right) are part of Kozushima volcano in the northern Izu Islands. The small 4 x 6 km island formed by a cluster of rhyolitic lava domes and associated pyroclastic deposits. The youngest and largest dome, Tenjoyama, occupies the central portion of the island. Most of the older domes are to the north. Two historical eruptions occurred during the 9th century. Photo by Ichio Moriya (Kanazawa University).
