Jason II was able to make extended observations at Brimstone Pit during dive J2-192. The science team witnessed repeated pulses of lava rising in the vent that were initially crusted over but would quickly crack open and expel their molten contents. Violently expanding volcanic gases break apart and propel pieces of the lava crust in all directions. Video courtesy of Submarine Ring of Fire 2006 Exploration, NOAA Vents Program.
