The weather around Redoubt volcano in Alaska cleared over the last few days to reveal a prominent steam plume, but this does not indicate a renewal of activity. The Alaska Volcano Observatory has confirmed that the heating of fresh snowfall on the summit is the source of the plume, and that seismic activity at the volcano continues to decline. The most recent AVO status reports say that the lava dome is cooling, and that, while the threat of a collapse remains, that threat is declining over time.

Redoubt is at alert level Yellow/Advisory, but Chris Waythomas of the AVO is quoted by the Peninsula Clarion as saying ‘It’s headed toward background activity, though. I wouldn’t be surprised if it was downgraded to green next month’.
