Video taken by ROPOS at the edge of Brimstone Pit near the summit of NW Rota 1 volcano, showing ash and sulfur-laden eruptions from the crater. The crater is at a depth of 555 m. The yellow color of the billowing clouds is due to droplets of molten sulfur in the plume bursts. Video courtesy of Submarine Ring of Fire 2004 Exploration, NOAA Vents Program.
