The Alaska Volcano Observatory reports that there was a small explosive event at Redoubt early this morning that produced an ash plume to not more than 15000 feet (4500 metres). It happened at 05:12 AKDT (13:12 GMT) and lasted about 10 minutes. The AVO Volcanic Activity Notice for this event is here.
Before this event seismicity had been generally low-level, with occasional small quakes; afterwards seismicity was elevated for a couple of hours, with low-amplitude tremor evident on the webicorder traces, but had settled back down by around 07:30. The AVO reports that ‘It is unlikely there will be any impact from this event’.
UPDATE: Another small explosion at around 10:17 Alaska time (18:17 GMT) – thanks to Boris Behncke for the tip. Quite intense tremor still ongoing at the time of posting (18:39 GMT), very visible on the RDN trace. Erik Klemetti has just put up a very informative post on Redoubt at Eruptions, saying it’s likely we’ll be seeing a lot more of this kind of thing in the weeks and months to come. [N.B. I won’t be able to post any more tonight – perhaps it’s just as well, WordPress seems to be broken and everything is taking ten times longer than it should. I’ll catch up with things tomorrow.]
