Detailed Description
With lava retreating deeper into the Halema'uma'u vent cavity over the past two days, the cavity walls have experienced more frequent collapses. At 2:23pm today (March 7), a collapse from the upper portion of the vent cavity produced a robust brown plume, but did not eject any large particles.
