South Sarigan seamount, rising to within about 184 meters of the sea surface 12 km south of Sarigan Island, was the site of a short-term explosive submarine eruption in May 2010 that produced a plume of ash and steam to 12 km altitude. Sidescan Sonar imagery taken in 2003 shows an irregular summit with multiple peaks, including a possibly young cone at about 350 m depth, and flank morphology suggests it is a frequently active volcano.
