Data from the Global Volcanism Program of the Smithsonian Institution
Details for: East Diamante
Active smoker chimneys precipitating iron, copper and zinc sulfides from 230°C fluid are found at the Black Forest hydrothermal area within the submarine caldera of East Diamante volcano. They are 9 m tall from the base to the top. The submarine volcano contains an elongated NE-SW-trending caldera with a pronounced rim on the NE side. A complex of lava domes constructed in the center of the caldera is the site of several hydrothermal areas. Image courtesy of Submarine Ring of Fire 2004 Exploration, NOAA Vents Program.

The dacitic East Diamante submarine volcano contains an elongated NE-SW-trending caldera with a pronounced rim on the NE side. A large post-caldera cone lies on the SW caldera rim, and a complex of lava domes was constructed in the center of the caldera. Several areas of hydrothermal activity including "black smoker" sulfide chimneys at the Black Forest site were detected on the central dome complex at depths of only a few hundred meters. The summit extends to within 127 m of the ocean surface. West Diamante seamount lies 28 km W, with the much smaller Middle Diamante about 15 km W.
