I'll be "off the grid" for the weekend at a wedding, so I thought I'd leave this open for any Redoubt news Eruptions readers hear over the weekend. Feel free to leave comments…
Back in a former life, I was really into radio and music. Such an existence calls for many lists of rankings: "Best albums of 2004", "All time greatest soul singers", "Worst album covers of the 1980s". And, although I love a list as much as the next person, I tend to find lists appalling. Why?…

Following the provided script, Redoubt erupted again last night, producing a 32,000 foot / 10,000 meter ash column that prompted a new ash fall warning for the Kenai Peninsula area. Thus far, though, there have been few reports of major damage being…

I don't have many details, but the largest eruption so far in this eruptive stage at Redoubt occurred at 9:24 AM (Alaska Time), producing a 65,000 foot / 20,000 meter ash column! Yes, you read that right, a 20-km ash column! This is by far the largest ash…

Based on the current levels of seismicity over the past 36 hours, AVO has returned Redoubt to Orange/Watch status from Red/Warning. This doesn't mean that the eruption is over, just that things have settled down a bit. Flights to and from Anchorage…
Its been a busy week for volcanoes between the headline capturing Tongan and Alaska eruptions. Catch up on what you might have missed with the latest SI/USGS Weekly Volcano Report (for 3/18-3/24). Highlights (beyond Hunga Tonga Hunga Ha'apai and Redoubt) include:
Galeras, Colombia has settled down…
Redoubt seems to be setting its pattern for this part of the new eruptive period. There was another small explosion this morning that produced at 15,000 foot / 5,000 meter ash column that moved to the NNW. The seismicity has settled down since the early morning eruption today (3/25) as well.
These…
Mauna Loa fire fountains in 1984
For those of you looking for some non-Redoubt-related volcano news, you can take a look at the 25th anniversary of the last eruption at Mauna Loa (there is some nice video footage provided by KHNL if you follow the link). By no means is this volcano "dormant", but…

Redoubt has simmered down some today with no new eruptions since yesterday evening. AVO's field crew not only fixed the Hut webcam, but also spotted massive lahar deposits (see above) in the Drift River valley that traveled 35 kilometers downstream…

AVO has posted a series of images taken around Redoubt and around the Cook Inlet since the new eruptions started the night of March 22nd. You can begin to see the extent of the ash fall, what the explosions have done to the Drift Glacier and the new deposits in the Drift…
The Hut webcam at Redoubt that has a great view of the hydrothermal vents near the 1989-90 domes - and the area where the current eruption is likely to be sourced - is back online. So far, we can see what looks like lahar deposits on the lower left-hand flanks of the volcano in the stream channels…
The Anchorage Daily News has a report that 16 Alaskan representatives got stuck in Anchorage after the eruption started. They were headed to Juneau to vote on Alaska accepting stimulus money ("volcano monitoring" anyone?), but they were on one of the many flights canceled by Alaska Airlines today…

I'm breaking this out of the comments of the "Redoubt Erupts!" post just to keep things up-to-date.
As of now, we know:
At least 5 explosions have occurred as part of the eruption
Ash has drifted to the…
Mt. Redoubt in March 2009, prior to erupting
At ~10:30 PM (Alaskan Time) last night, Mt. Redoubt erupted. AVO and the Anchorage VAAC issued a Red Alert for ash as high as 50,000 feet (15,000 meters) around the volcano. Information is scarce about the exact nature of the ash cloud because of the…
Seismicity has increased dramatically at Redoubt in Alaska over the last 24 hours, so AVO has put the volcano back on Orange/ Watch status. They say the tremors being felt now could be signs to an impending eruption (days to weeks), especially after the other events of the past week. Stay tuned! (…
So, as I am apt to do from time to time, I was wandering the interweb and stumbled across the FEMA (Federal Emergency Management Agency) for Kids website. Naturally, I thought, what do they have to say about, oh, I don't know, volcanoes. Well, was I in for a doozy!
FEMA, in its infinite wisdom,…
Now that people have been able to get a better look at the are about Hunga Tonga Hunga Ha'apai, we've been able to get a better idea of what sort of eruption occurred. The explosions and ash/tephra from the eruption have all but wiped out life on Hunga Ha'aapai, as the island contains one of the…
This falls under the category of "when it rains, it pours". A M7.9 earthquake struck today in the Tongan arc. It doesn't appear to be related to the Hunga Tonga Hunga Ha'apai eruption as it occurred a few hundred kilometers to the SSE of the volcano (remember folks, correlation does not mean…
Mixing volcanoes and oceans seem to always produce exciting results. Whether it is something as simple as the ocean entry of a lava to something as impressive as a new island emerging, formed by volcanic eruption. Back in the 1960s, a previous unknown undersea volcano off the coast of Iceland…

After an exciting few days ... well, OK ... after an exciting few hours on Sunday, AVO has decided to lower the alert level at Redoubt in Alaska to Yellow/Advisory. The alert level was lowered last week after seismicity at the volcano returned to normal after…
I probably won't comment too much on these, but if you need a rundown on every volcanic rumbling on the planet in a given week, nothing is better that the weekly reports compiled by the USGS/Smithsonian Global Volcanism Program. You can check them out both through the GVP website and as a…
The eruption of Hunga Tonga Hunga Ha'apai volcano in Tonga looks to be a big one. Keleti Mafi, head of the Tongan geological service, calls this "a very significant eruption, on quite a large scale", which is no surprise considering some of the spectacular picture we saw of the eruption yesterday…

Hunga Tonga-Hunga Ha'apai (how's that for a name?), a shallow seamount in Tonga, appears to have erupted. An air passenger snapped some pictures of an eruption occurring in the ocean between the Tongatapu and Vava'u and pilots in the area report that (unsurprisingly), the…
Now that Redoubt has decided that Yellow/Advisory is not to its likely and has returned to an Orange/Watch status, I'll continue bringing new updates of the volcano has events unfold.
And nothing much has unfolded since the phreatic explosion that occurred on Sunday. The current state of the…
I've finished migrating my archives of the ol' Wordpress Eruptions (since May 2008), so if you're looking for more information, try clicking "Archives" at the top of the page and wander through there. I will be updating the archives with category linked for each volcano, but that might take a while…
Oh yes, and if you're into that sort of thing, you can follow Eruptions on the Facebook as well. I hear its on the interweb these days, so thats cool. Just click on the "Networked Blogs" link in the bottom left-hand side of this page (below the world map).

As with most disasters, the best way to prevent a Katrina-like catastrophe is preparedness. The best successes in volcanic mitigation have been in places where the combination of monitoring, communications and practice fit together like so many legos in a set, allowing…

So much for my oh-so-eloquent eulogy for early 2009 activity at Redoubt.
AVO reports that it appears that the volcano has potentially erupted - or at least released a lot of steam and (possibly) ash.
Seismic…
I missed this the first time, but Click & Clack from NPR's Car Talk answered a question about how to volcano-proof your car.
If you want to hear it, click here. As usual, the guys in Cambridge (our fair city) do an excellent job with the information and the humor.

I've been following the waxing and waning of activity at Mt. Redoubt in Alaska for the past two months like many of you have. For a time there, the volcano…
