Brothers
About Brothers
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.
