Ringkasan geologi
Esmeralda Bank is a massive submarine volcano with three cones oriented N-S over about 15 km. The high points on the crater rim of the large middle edifice, with a collapse scarp open to the W, are about 75 m below the ocean surface. Frequent sulfur-rich surface bubbling and water discoloration have been observed, which have variously been attributed to eruptive events or fumarolic activity.
