USGS video still: robust brown plume associated with a hybrid seismic event at 11:03 am

The Hawaiian Volcano Observatory on the Big Island of Hawaii has released video of a robust brown plume associated with a "hybrid seismic event" on the summit of Kilauea at 11:03 am.

The HVO website says brown plumes like this one have appeared occasionally throughout the past year of eruptive activity at the summit, and are often associated with rockfalls.

According to the HVO daily update, Wednesday's activity started with at least two more dusty plumes followed by a larger collapse at 11:03 am and a large, dense, brown plume; there were several more brown plumes over the next two hours before settling to a white plume moving southwest from the crater.
