Gunung Rausu

Rausudake

Stratovolkan · Japan · 1660 m

Rausudake, seen here from the SW at Shiretoko Pass, is a small cone in NE Hokkaido. It is located 5 km SW of Shiretoko-Iozan volcano along the crest of the elongated NE-trending ridge forming the Shiretoko Peninsula. Explosive eruptions have taken place several times during the Holocene, including eruptions of pumiceous tephras about 2,200 and 1,500 years ago.

Ringkasan geologi

Rausudake is an andesitic-to-dacitic stratovolcano with summit lava domes on the Shiretoko Peninsula in NE Hokkaido. The 1660-m-high volcano is located along a ridge 5 km SW of Shiretoko-Iozan volcano, the NE-most Holocene volcano in Hokkaido. Young lava flows descend the NW flank and broad areas along the SE flank, and an older lava flow traveled about 9 km W, reaching the coast of the Sea of Okhotsk along a broad front. Eruptions produced pumiceous tephras with associated pyroclastic flows about 2200, 1400, and 800 years ago. Recent work has documented a pyroclastic-flow deposit that overlies the 1739 tephra from Tarumai volcano in SW Hokkaido. Stratigraphic relationships place this eruption, the most recent known from Rausudake, between about 1750 and 1850 CE.
