Geological summary

Ulleungdo, also known as Ulreungdo, is a 10-km-wide island about 100 km E of the central Korean Peninsula. The trachyandesitic stratovolcano is truncated by the Nari caldera. A major phonolitic explosive eruption at the beginning of the Holocene from Nari caldera produced pyroclastic flows and deposited ash in central Honshu, Japan.
