Brothers Seamount

Brothers

Kaldera · New Zealand · 1350 m (bawah laut)

Submarine hydrothermal activity occurs at Brothers volcano, as seen here at this tall (up to 4 m high), active black smoker chimney, which is part of a large field of vents on the NW caldera wall. The oval-shaped caldera is 3-3.5 km wide and contains a post-caldera lava dome constructed on the S caldera floor.

Ringkasan geologi

The submarine Brothers volcano, located NE of the Healy submarine volcano, contains an oval-shaped summit caldera 3-3.5 km elongated NW-SE. The high point of the dominantly dacitic edifice lies on the NW caldera rim at about 1,350 m below the ocean surface. The caldera floor is at about 1,850 m depth, and a post-caldera lava dome partially merges with the southern caldera wall. There is significant hydrothermal activity, including a large field of "black smoker" vents on the NW caldera wall and vents on the post-caldera dome.
