Mariana Volcanic Chain | ROPOS at the edge of Brimstone Pit
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 meters. The yellow color of the billowing clouds is due to droplets of molten sulfur in the plume bursts.
