Redoubt 27 March 2009 eruption cloud (photographer Dennis Anderson)
Redoubt’s eruption cloud from the 27 March 2009 19:25 AKDT eruption, photographed at 19:57 from Homer, Alaska (photographer: Dennis Anderson, auroradude.com).

Redoubt has erupted explosively three times in the last seven hours, reports the Alaska Volcano Observatory. An eruption at 17:35 AKDT (01:35 GMT) produced an eruption cloud to 40000 feet (12200 metres) above sea level; another eruption at 19:25 AKDT (03:25 GMT) sent up a plume to 51000 feet (15500 metres); and a third, beginning at 23:20 AKDT (07:20 GMT), has produced a cloud that has reached 40000 feet (12200 metres).

UPDATE: A further eruption began at 01:20 AKDT (09:20 GMT), with an eruption cloud reported up to 50000 feet above sea level (15200 metres).

Unfortunately the AVO Hut Webcam has been blacked out by ash since around 18:00 local time yesterday. The Rig Webcam in Cook Inlet has had a very misty and cloudy view over the past few daylight hours, but the vague shape of the eruption plume can be made out in shots from around 03:44 GMT onwards.

Was the RDN webrecorded signal lost?

5. volcanism - 28 March 2009

Other AVO webicorder traces are currently missing as well – I suspect a technical fault at the Observatory.
