Details for: Unzendake
The large Unzen volcanic complex comprises much of the Shimabara Peninsula east of Nagasaki. Three large stratovolcanoes with complex structures, Kinugasa on the north, Fugen-dake in the east-center, and Kusenbu on the south, form topographic highs on the peninsula, seen here from across Shimabara Bay to its east. Historical eruptive activity has been restricted to the summit and flanks of Fugen-dake. The latest activity during 1990-95 formed a lava dome at the summit, accompanied by pyroclastic flows.
