It’s a good week for gelogy nerds. After last week’s undersea volcanic eruption in the South Pacific, the Alaskan volcano Mt. Redoubt erupted violently several times last weekend, and continues to rumble. Ash clouds rose to about 16 km according the Alaskan Volcano Observatory (AVO) and the eruption caused significant flooding (see this cool picture). The Alaskan volcanoes form part of the Pacific Ring of Fire which is littered with active volcanoes and a frequent site for earthquakes and eruptions.

Check out the AVO page on Redoubt for updates or follow on Twitter.

**Update, 29/03/09** Redoubt isn’t done erupting yet, more explosive eruptions took place in the last couple of days. The AVO Twitter feed is the best way of keeping up to date!

**Update, 30 March 09**. Explosive eruptions have continued at Redoubt in thel last few days and AVO is reporting the first ash falling on Achorage. There’s no danger to the population though. More spectacular pictures have appeared on the AVO website, this one is particularly striking.

Hi Sarah,

Been following on Twitter and the blog. I used to live in AK. We went through one Mt. Redoubt threat but nothing happened. Looks like it was a bit more active this time around. My brother still lives there and said some of the media reports are a bit overblown. He said many are making it sound like Anchorage is Pompeii. Not quite.

Take care. Clear skies.

Hi Mark,
Thanks – good to get a more local perspective. Living in Western EuropeI’m far removed from any kind of seismic activity so earthquakes and volcanoes sound *very* dramatic to me 🙂 The images are pretty spectacular though and I’m pleased that no one in Alaska is in any danger from the activity (Anchorage turning into Pompeii would be really bad)
