Sorry about the brevity of this update, but I'm exhausted.

At this time, based on AVO analysis of satellite data, ash is continuing to erupt from a composite cinder and spatter cone called Cone D in the eastern portion of the 6-mile wide caldera or crater of Okmok. It appears that the eruption is very water-rich due to interaction of rising magma with very shallow groundwater and surficial water inside the caldera. We have few direct observations into the caldera and details of the current event remain unknown.
The current activity differs in character from the past three significant eruptions at Okmok in 1945, 1958, and 1997. All of these eruptions occurred at a cinder and spatter cone on the far western portion of the caldera floor, Cone A. In general, each eruption was mildly to moderately explosive with most ash clouds produced rising ...
