Eastern view of Unzen Volcano in the Shimabara Peninsula, Kyushu, SW Japan. New lava domes with the thick apron of volcanic debris have formed near the summit of Mt. Fugen (1.359 m) since 20 May 1991. Rockfalls from the fronts of domes descended as pyroclastic flows along the Mizunashi River (straight toward readers) and Oshigadani Valley (curved in the clockwise direction).
