Bogoslof volcano (Aleutian Islands): short but violent explosive eruption reported

Ash plume from Bogoslof volcano on satellite imagery (image: NOAA/CIMSS)An eruption occurred at the volcano early this morning (at 01 am UTC). A brief, but relatively strong explosion seems to have produced a short-lived ash plume which was spotted on satellite data and by pilots en route in the area.
According to this data, an ash column rose to approx. 10 km altitude and quickly dissipated to the south.
There is no monitoring of the volcano on the remote island itself and not much is known about its activity and typical behavior. There are no details available about the nature of today's event. So far, no new ash plumes have become visible, which could mean that the explosion was an isolated event.
The last known eruption of Bogoslof volcano was in 1992 near the northern shore of the small island. A vent breached the sea surface producing surtseyan activity before building a new lava dome that eventually reached about 150 m height. Similar events had also occurred in 1927 and 1786, but only small remnants of the edifices produced by those earlier eruptions have survived the erosive action of the arctic ocean.
