Steam rises from fumaroles on a SW-flank crater of Sashiusudake volcano on central Iturup Island with the summit crater visible at the top. A broad low lava dome, 500 m wide and 40-50 m high, occupies the crater, which has produced lava flows that cover wide areas on the northern and western flanks.
