Blowing steam

This Quicktime movie (at x2 speed) shows a small explosive event in the Halema`uma`u vent at 9:20am.  The explosion was immediately preceded by a portion of the vent rim collapsing into the vent cavity.  The brown plume rises rapidly from the vent, and in the full resolution video large particles can be seen ejected in front of the plume.  In the video shown here, it is possible to see some of these particles impact the crater wall—look for several small white puffs to appear on the crater wall just ahead of the rising brown plume (about 7-9 seconds into the video clip).  No ejecta was found at the Halema`uma`u Overlook, indicating that few, if any particles, reached the crater rim.
