Jason II approaches Brimstone Pit for the first time during our 2006 expedition and finds that the south flank of the cone has completely fallen away. Only a remnant of the north wall remains. At first, not much is happening at the vent, but gradually a degassing event starts releasing a huge number of bubbles (probably CO2).
