- VolcanoBaransky volcano (Sashiusu-dake in Japanese) is a stratovolcano in the center of Iturup Island, southern Kuriles. Only one historical eruption occurred in 1951 and consisted of weak explosions in the summit crater. Strong fumarolic activity is in the summit and several flank craters. A geothermal field is found on the SW flank and contains hot springs and geysers. During a geothermal exploration in 1992 in this field, a small hydrothermal explosion took place inside an exploratory well and the exploration was abandoned.
Volcano type stratovolcano normal or dormant Location Russia Summit elevation 1132 m / 3,714 ft Baransky volcano eruptions 1951 Typical eruption style explosiveThe Baransky stratovolcano was built on top of an older eroded volcano. It has a young summit lava dome cut by a NW-trending chain of small explosion craters. A group of flank cones farther to the NW with a similar NW-SE orientation is partially surrounded by lava flows from the central crater of the andesitic-dacitic volcano. Lava flows from Baransky descended 4-5 km SE to reach the Pacific Ocean along a broad front.
