Ruby

Stratovolkan · United States · 174 m (bawah laut)

Ruby submarine volcano in the southern Mariana arc is seen in this bathymetric data looking from the NW with 2x vertical exaggeration. Depths in this image range from 184 to 2,955 m, and it rises to within 230 m of the ocean surface NW of Saipan. There was an eruption detected in 1966 by sonar signals. In 1995 submarine explosions were heard, accompanied by a fish kill, sulfurous odors, bubbling water, and the detection of volcanic tremor.
