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. Strong fumarolic activity continues from the summit and flank craters, and the SW-flank geothermal field contains hot springs and geysers.
