Video of the sixth eruption, from the Alaska Volcano observatory webcam system. (h/t to Ron De Haan)
There is sound in this video.
As first noticed by WUWT commenter Crosspatch last night, from seismic data, it appears Mt. Redoubt has erupted:
Crossptach at 9:41pm
Looking at this Redoubt webicorder it looks like an eruption of some sort might have started at around 2045UTC. It’s dark there now, so we won’t know until morning.

Because the eruptions happened at night, so far we don’t have any current photography. Hopefully soon. The radar image above shows the plume clearly though. Here is a 40 frame loop showing the eruptions. (h/t Tom Woods) – Anthony
Noon Update: The most recent volcanic ash advisory from Anchorage VAAC, issued at 17:25 GMT (09:25 local time) gives the plume altitude as FL600, which is 60000 feet ot 18 kilometers (h/t to The Volcansim Blog )
FoxNews: Alaska’s Mt. Redoubt volcano erupted late [Sunday and early Monday] in “four large explosions,” sending an ash plume an estimated 9 miles into the air, the Alaska Volcano Observatory reported.
“The ash cloud went to 50,000 feet, and it’s currently drifting toward the north, northeast,” said Janet Schaefer, a geologist with the Alaska Volcano Observatory.
Geologists at the observatory say the volcano, located 100 miles southwest of Anchorage, erupted four times, from 10:30 p.m. to 1:40 a.m. local time.
“This is a fairly large eruption, close to the larger cities in Alaska,” Geophysicist John Power said.
The current wind patterns are taking the ash cloud away from Anchorage and instead heading toward Willow and Talkneetna, two communities near Mount McKinley, North America’s largest mountain in Denali National Park.

“erupted late Monday and early Tuesday ”
It’s not Tuesday yet, unless I was abducted by aliens and missed a day….
REPLY: Some reporter obviously thinks it’s on the other side of the international dateline – Anthony
REPLY2: Doing some checking it “appears” the error may have been initially with AP as I’ve found a few nearly identical stories that now say late “Sunday and early Monday”. If it was an automated newsfeed update for the Fox web page overnight it is likely it went unnoticed. I didn’t notice myself because I was busy hunting for imagery. I’ve put the correct days in the story [in brackets] so as not to lead more readers astray. – Anthony
I wouldn’t trust the FoxNews report as to the number of explosions since they can’t even get the day correct. Perhaps they used a volcano eruption modeling program to predict that the volcano will erupt tonight and tomorrow. And since computer models are more important than facts…
REPLY: here is an AP story that confirms the 4 eruptions

A news confirmation
http://www.irishtimes.com/newspaper/breaking/2009/0323/breaking29.htm
The station RSO webicorder located close to the Redoubt summit looks like it flat lined at about 04:45.
The first report I read said 20,000 ft. The report Anthony cites says 50,000 ft.
Big difference!
I cannot wait (well, I guess I have to) until we see some daylight images of this.
REPLY: The Alaska Volcano Observatory says “The onset of the tremor was associated with a small explosion that produced a plume of gas and ash that rose to about 15,000 feet above sea level and deposited a trace amount of ash over the summit-crater floor and down the south flank of the volcano to about 3,000 feet.”
Though a TV station in Kansas reports: “9 miles high” http://www.kake.com/news/headlines/41677847.html
Maybe there is some confusion over the volcano elevation and height of the plume, the volcano summit is 10Kfeet+ (2 miles) Maybe the reporter was on the telephone and heard “15,000” feet as “50,000 feet”…hard to know at this point – Anthony
Oh there goes my Tomatoes-gotta get that greenhouse finished..
(Between snowstorms…)
Gives the AGW team a perfect excuse for any cooling in the future.
Mt. Redoubt in Alaska erupts…
Finally!!!!
How much in carbon offsets do we need buy to offset this?
Is Mt. Redoubt in violation of her Cap and Trade regulations and limits?

The report you cited is over a week old, the current report is here and says 50,000′.

I don’t know if the figure is accurate but from the Redoubt Volcano Activity Notifications
http://www.avo.alaska.edu/activity/Redoubt.php
2009-03-22 23:26:32 – VAN/VONA
The eruption of Mt. Redoubt continues. The height of the eruption cloud is estimated to be 50,000 ft above sea level. Further reports will be issued as more information becomes available.

LOL at the statement here:
Redoubt is currently exhibiting signs of unrest, although as of 9:09 am AKDT, March 9, 2009, it has not erupted.
Thanks for putting the time up! No updates for 2 weeks, but we know what time it was…
Your radar trace appears to have been taken without acknowledgement from this Volcanism Blog post:
http://volcanism.wordpress.com/2009/03/23/redoubt-eruption-update/
The caption comes from there too. That would be why it says ‘click for latest radar image’: that works on the original post, but not on your post.
REPLY: the image was emailed to me with a description, and since it was NOAA/NWS radar (obviously) I didn’t even consider the source to be elsewhere. But now that it has been pointed out to me I gave The Vulcanism Blog a h/t and link. Thanks for pointing this out! – Anthony
Just for accuracy, that picture appears to have been taken April 21, 1990.

Absolutely incredible image, anyway… it looks exactly like a nuclear mushroom cloud. Which reminds me… how many times have we heard that the first atomic tests created “something never seen before: a mushroom cloud”… ?
Ted Annonson (06:38:49) :

As this is a high latitude eruption, my understanding is that the ash/aerosols will be held in the N. Hemisphere and so there will be no/limited global effect.

Well the sooner that we reach the tipping point, the sooner they will have to drop their carbon-taxes and cap and trade rip-off schemes. After all the situation we will find ourselves in after this tipping point is hundreds of millions of people asking, “What is the point in continuing to pay for something that we already know has not worked and will never work? We might as well enjoy using what energy is left to us, before we all perish and the earth can heal perfectly well after we are all gone.”
Who is going to pay carbon taxes if there is 0% chance that they will work as we passed the “tipping point”?
This is why I predict that we will NEVER reach the tipping point. Once we do, Al-Gore’s cap and trade business model collapses! We will remain continually at a state of being between 3 and 8 years from a tipping point. Like a donkey with a carrot and a stick, they try to lead us further into their scam!
Also these elitists of the AGW religion will never allow a tipping point to be reached, because they will have a very hard time explaining why the earth is NOT in runaway heating mode years after the tipping point was passed!
I hope there is a lot of dust from the eruption so that it can contribute to additional global cooling.

“The station RSO webicorder located close to the Redoubt summit looks like it flat lined at about 04:45”.
It’s toasted, probably by a pyroclastic flow.

Anyhow, daytime is arriving so, if visibility allows it, we can have a look at the web cam soon.
Clearly this is because of global warming.
“A warmer world could be a more explosive one. Global warming is having a much more profound effect than just melting ice caps – it is melting magma too.”
http://www.newscientist.com/article/dn13583-melting-ice-caps-may-trigger-more-volcanic-eruptions.html
Is that not a negative feedback?
Or maybe its the magma that melts the ice in the first place.
“THERE’S a monster under the ice. The discovery of a volcano in Antarctica could explain why a nearby glacier has been surging so quickly into the sea.”
http://www.newscientist.com/article/mg19726403.100-antarctic-volcano-gives-glacier-the-slip.html
This is interesting too.

O/T to BernardP (06:17:07) :
The theme of the Sharon Begley report in Newsweek is correct, namely “the need for Nobel-caliber discoveries” if human inputs of CO2 are to be brought low. Of course the premise is wrong – we really don’t need to do that – and Al Gore, our Nobel prize winner, has never discovered anything –not even the internet.
It may be old, but that picture is mighty impressive.
