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.

Ash ect…might prevent “extra” NH ice melt this summer up there. Cryosphere ain’t prepared to compare recent ice 2009 with past anymore. Reason = satellite clitch please give benefit of doubt. AMSR shows levels similar to 2008 so would expect a gradual return to “normal” melting over next few years. On a general note because climate change is probably measured in 1000’s years I think both pro-AGW and skeptics will start tiring of the whole thing and slowly forget about even looking at this and other “climate sites”, mainly because things will NOT change in our lifetimes. We will have to find other distractions.. LOL
Since volcanic eruptions can be driven by magma degassing as it rises and the containment pressure drops, releasing CO2, I expect that Alaska will have to make some kind carbon offset payment to the UN. Of course the Secret Global Cooling that is underway probably means that the lava flows will be more like warm porridge, so perhaps it will balance out. 🙂
These events are awesome. From a distance…
This volcanic eruption will exert a downward pressure on global temperatures. Combined with the current ten year cooling trend, this will confirm that Albert Gore’s “outing” of the global warming threat has actually, and miraculously, resulted in a reversal of the warming. Albert Gore has actually, and miraculously, saved the planet from disaster! He should be granted many more Oscars and Nobel prizes, and a Presidential Medal of Freedom to boot! And then he should be retired to a life of ease on his Tennessee plantation. His earthly work is over!
Posthumous sainthood for Albert must be left up to the Roman Catholic Church, but as a person raised in the Methodist faith, I heartily recommend it.
“This volcanic eruption will exert a downward pressure on global temperatures. ”
On what is that prediction based? There is not enough materiel yet erupted to exert downward pressure on anything, let alone “global temperatures”
Now if there is a HUGE eruption (something on the scale of Pinatubo or larger) I might agree with that statement but so far, what we have seen is pretty much nothing.
SO2 is more climate changing from volcanism than CO2 is … at least in brief episodes we generally see. I am not talking about flood basalt eruptions that might go on for years but we haven’t seen one of those in a very long time.
Mt. Etna releases 10 times more SO2 than all of Sweden emits to quote a recent article.
Volcanoes are net coolers of climate, in my opinion.
” Ben Lawson (20:55:10) : I expect that Alaska will have to make some kind carbon offset payment to the UN.”
Have to?
“Dan Rogers (21:17:41) : And then he should be retired to a life of ease on his Tennessee plantation. His earthly work is over!”
No, that man will never go away.
I must confess complete ignorance on this subject of geologic/volcanic activity as related to solar max and min as hinted to earlier by Robert Bateman. Does anyone have data one way or the other? Is there a valid theory for this? Perhaps someone with a bit more knowledge could post some evidence on this or debunk it. Interesting to discuss if nothing else!
“Ben Lawson (20:55:10) : Secret Global Cooling”
Secret? There are some who try to keep it secret. Of course they would be the type who care more about agendas of power over people than telling the truth.
Here’s some of the talk of that cooling :
A cooler summer in the North as a result of the eruption should do wonders for Arctic sea ice. I wonder if increased vulcanism could be a negative feedback?
A bit off topic, but I had a dream that in 50 years as it is clear we are entering the next ice age, that the history of this time will indicate that it was due to the selfish deniers refusal to accept that CO2 causes global cooling and reduce their energy consumption. CO2 causes global cooling, always has, always will. Thats why ice core data shows CO2 lags temperature. It is a negative feedback. Imagine those dumb or evil deniers, who are prosecuted for their beliefs in this dream. If my dream is true, the Winstons of 1984 will have a lot of stuff to rewrite and a lot of stuff that needs to go down the memory hole.
Don’t laugh at my dream. It might be true in this Orwellian world of ours. I tell you, I woke up in a cold sweat, no pun intended. What if we should reduce CO2 emissions, but for the opposite reason, an ice age that history says will come would be accelerated by mans emissions.
Mindful of recent links/comments on WUWT that were discussing a possible mega-scale realtionship between the sun’s orbital variatons around the centre of mass of the solar system, the rotational period of the earth, and the oceanic oscillations, I have just come across a reference to this papaer:
http://adsabs.harvard.edu/abs/1989JGR….9417371S
which notes a coincidence between cycles of solar activity (susnpot minima) and terrestrial volcanic activitry (eruptive maxima), and postulates a common larger scale origin for this correlation.

“I must confess complete ignorance on this subject of geologic/volcanic activity as related to solar max ”
Don’t fret. Most of the scientific community is with you. There probably isn’t any linkage between solar activity and volcanic activity. At least none anyone has been able to prove.
There were plenty of eruptions around the last solar maximum.

Not while the alarmists want to tax us for breathing and our livestock for flatulence. Personally, I won’t be satisfied until I see fraud trials.
On SBS News tonight here in Australia they are still spouting tripe about CO2 and climate change. Now “scientists” are wanting to “engineer the climate” because temperarures and CO2 rates are soaring by doing things like;
Spiking oceans with iron fluid to encourage algae to grow faster and absorb more CO2 (Actual experiment produced unpredicted results – No kidding).
Spraying oceans with iron filings.
Developing artificial trees.
Deploying mirrors in space to reflect the energy from the sun.
Simulating volcanos by spraying “dust” in to the atmosphere by aircraft.
Developing huge ships that spray the air with sea water to create clouds.
The mind boggles!
John F. Hultquist (12:15:28) :
RE: B Kerr (11:26:01) : Lots of tuff.
“We made it home before it got dark as the cloud went over. We had about ½ inch of very fine glassy crystals before it was done.”
Sounds terrifying.
Glad you got through it.
“The Catlin folk are much farther away (~1,500 miles) so I don’t think it will distract them much from their primary objective – making headlines about silly science. ”
I’m not sure if the 1,500 miles distance is enough, which could be tuff on them.
In 1845 the people in Orkney, north of Scotland, woke up to find their lovely green fields had turned black over night. Hekla in Iceland had done one of its tricks again. There is evidence that the northern Neolithic culture came dramatically end when Hekla? blasted rock and ash over northern Scotland into the North Sea.
I also read that our ancestors called the “Dark Ages” dark.
It would appear that northern Europe was actually dark.
Volcanoes have a great effect on human existence.
Naaaa 1,500 miles is nothing.
BRIAN M FLYNN: Alan Robock has since changed his opinion about high latitude volcanic eruptions. (This assumes the following is the most recent paper on the subject. Opinions do change, as you know.) Robock was part of the group that prepared the 2005 Oman et al paper “Climatic response to high-latitude volcanic eruptions”.
http://climate.envsci.rutgers.edu/pdf/Oman2004JD005487.pdf
They write in the abstract, “The results of these simulations do not show a positive Arctic Oscillation response like past simulations of tropical volcanic eruptions, but we did find significant cooling over southern Asia during
the boreal winter.”
And contrary to what I understood from earlier papers, based on this study, high latitude eruptions like Katmai can have an effect on the Northern Hemisphere radiative forcings. But the question that needs to be answered now is, how closely does Redoubt match Katmai? Is it similar in scale or significantly smaller, larger?
I guess we’ll just have to wait and see how well the GISS Model E predicts the response to Katmai-like eruptions.
Re the possible correlation of geologic/volcanic activity with solar min/max.
How about the correlation of volcanic activity with bovine flatulence?
Sorry for my irreverence, but this global warming debate is getting crazier every day.
There is now talk of trade wars with China if they fail to enact Kyoto-type CO2 controls – even though the evidence for catastrophic humanmade global warming was never strong, and is getting even weaker as Earth cools.
Trade wars over CO2 during a deep recession – that is almost certain to trigger another Great Depression.
We will look back at this global warming fiasco as the greatest scientific fraud of our times, and our grandchildren will gaze in wonder at our incredible foolishness.

According to the writings of Rhoades Fairbridge we are expected to experience increased volcanism and earthquakes during this phase of the retrograde motion of the sun around its’ barycenter.
I wonder how long before we see a long overdue tsunami in Hawaii. Apparently it’s not if but when.

When Mt St. Helens errupted, my grandfather collected the ash, mixed it with some kind of hardening substance, and inlaid it into diamond cutouts on his many of his gun stocks. He was a giant of a man with shoulders broader than any I have seen. He was always invited to go hunting because he was the only man who could cart an elk out of a ravine on his shoulders.
Pat (00:08:52) :
“They” also consider spiking dormant volcanoes with nukes to get them ‘started’.
Earthquakes and sunspots
Average sunspot count of 16.99 for top 12 earthquakes in the last century
Average sunspot count for period is 22.45

For its latitude, 60,000ft is well into the stratosphere:

Perhaps we’ve got another major volcano-induced cooling event coming.
