Submarine Ring of Fire 2004: NW Rota-1 Brimstone1
Watch a NOAA video podcast on the Submarine Ring of Fire 2004 (SRoF'04) expedition to the Mariana Arc. Video taken by the ROPOS ROV at the edge of Brimstone Pit near the summit of NW Rota-1 submarine volcano, showing ash and sulfur-laden eruptions from the crater. The crater is at a depth of 555 meters (1820 feet). The yellow color of the billowing clouds is due to droplets of molten sulfur in the plume bursts.
