Mount Shiretoko

Shiretoko-Iozan

Stratovolcano · Japan · 1562m

Shiretoko-Iozan is seen here in late spring from the Shiretoko-Goko on the W side of the volcano. It is located at the NE tip of Hokkaido on the Shiretoko Peninsula and is noted for the extrusion of molten sulfur during eruptions in 1889 and 1936. Two large craters at the summit open to the NW.

Geological summary

Shiretoko-Iozan, one of many Japanese "sulfur mountains," is noted for the extrusion of molten sulfur during eruptions in 1889 and 1936. Located at the NE tip of Hokkaido on the Shiretoko Peninsula, the andesitic volcano contains two large craters at the summit that are breached to the NW. The southern crater contains a small flat-topped lava dome. The main cone, Nakadake, was constructed NW of the headwalls of the two breached craters. Historical eruptions have originated from the southernmost of three explosion craters along a NNE-SSW line on the NW flank of the main cone.
