The series of strong explosions at the volcano continues.
Another event started at about 22:30 AKST local time last night (or this morning 07:30 UTC) and was detected in seismic and infrasound data from neighboring islands and produced lightning.
The highly explosive nature of the eruption is most likely due to the fact that the new vent is located at or near sea level and water-magma interaction increases the violent fragmentation of the erupted magma.
According to the Alaska Volcano Observatory, "seismic data suggest two strong eruptive pulses within that period, at 22:33-22:34 and 22:56 AKST (07:33-07:34 and 07:56 Jan 9 UTC), consistent with two distinct volcanic clouds observed in satellite images.
"The second cloud is larger and reached as high as 35,000 ft asl. Winds are blowing the volcanic clouds to the northwest.
"Additional explosive events at Bogoslof may occur without warning."
