The webcam views yesterday showed the familiar relatively small steam plume from the north face fumaroles. Seismicity was elevated, with prolonged episodes of sustained tremor, but the webicorder traces show that things have quietened down a bit now (i.e. from around 17:15 UTC / 0815 AKST yesterday). The volcano remains seismically active, however, with its internal rumblings significantly above normal background levels.

Here’s the latest statement (at the time of posting) from the Alaska Volcano Observatory website:

2009-02-08 22:21:56

Unrest at Redoubt Volcano continues. No eruption has occurred.

Seismicity at the volcano remains elevated.

The web camera is currently dark.

AVO staff members continue to monitor the volcano 24 hours a day.

[End of AVO statement.]

This is a more detailed statement issued earlier in the day:

2009-02-08 11:56:37 – Status Report

Unrest at Redoubt Volcano continues, though no eruption has yet occurred. Volcanic tremor is ongoing with variable amplitudes. Clear webcam images show a small steam plume.

Yesterday, observers on a gas-measurement flight reported continued steaming from the area around the 1989-90 lava dome, and continued water discharge along the Drift glacier. Gas data from the flight are still being processed.

AVO staff members continue to monitor the volcano 24 hours a day.

[End of AVO statement.]

Some images from 5 and 7 February have been posted on the AVO website and can be accessed via this page. They include some clear views of the ongoing fumarolic activity from the overflight on the latter date.
