South Sarigan Seamount

Stratovolkan · United States · 184 m (bawah laut)

Sidescan sonar imagery taken in 2003 shows South Sarigan seamount rising to within about 184 m of the ocean surface 12 km S of Sarigan Island. It was the site of an explosive submarine eruption in May 2010 that sent a plume of ash and steam to 12 km altitude. The seamount has an irregular summit with multiple peaks, including a possibly young cone at about 350 m depth, and flank morphology suggests it is frequently active.

South Sarigan seamount, rising to within about 184 m of the ocean surface 12 km S of Sarigan Island, was the site of a short 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.
