Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Sashiusudake [Baransky]
The SE slopes of Sashiusudake tower above steep sea cliffs along the Pacific Ocean coast of Iturup Island. Lava flows descended 4-5 km SE to reach the ocean along a broad front N of where this photo was taken. An eruption in 1951 consisted of weak explosive activity at the summit. Geothermal activity continues from the summit and flank craters, and the SW-flank geothermal field contains hot springs and geysers. Photo by Alexander Rybin, 1999 (Institute of Marine Geology and Geophysics, Yuzhno-Sakhalin).

The Sashiusudake (also known as Baransky) volcanic complex along the Pacific coast in the central part of Iturup Island consists of an eroded Pleistocene volcano that is capped by a Holocene stratovolcano. A young summit lava dome is 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 descended 4-5 km SE to reach the Pacific Ocean along a broad front. The only historical eruption occurred in 1951, when local inhabitants reported weak explosive activity at the summit. Strong solfataric activity continues from the summit and several flank craters, and the SW flank geothermal field contains hot springs and geysers. A small hydrothermal explosion took place in 1992 at an exploratory well in the SW-flank geothermal field.
