Fifth explosive eruption

Movie shows a small explosive eruption, at 7:37 am, from the vent in Halema`uma`u crater. The normal white degassing plume is rapidly overwhelmed by a more robust, ash-rich plume that rises rapidly from the vent. This is the fifth explosive eruption since the new vent at Halema`uma`u appeared in mid-March.

Movie shows an example of an ash-rich phase at Halema`uma`u crater. This event occurred at 3:40pm. These sporadic ash-rich phases are probably due to small rockfalls within the vent.
