I was chatting with a fellow from AVO and he called the simultaneous eruptions of Kasatochi, Cleveland and Okmok a "once in a millennia" event. So, enjoy it!
He also mentioned that the Kasatochi eruption released the most sulfur dioxide into the atmosphere since the 1991 Pinatubo eruption ... but we had an idea of that already.
And who knew that there has been uplift at Uturuncu in Bolivia? I sure didn't, but Steve Sparks does.

More to come later this week when I can go to all the Chaiten posters.

Jane Fraser, columnist in The Australian , writes a column based on "facts" she got from a chain email:

The Smithsonian gives the height of the volcano at 6008 meters or19,711 feet.
I should have mentioned that it is the height of the "Uturuncu in Bolivia" that is over 6000 meters (almost twenty-thousand feet high). There must be a massive amount of pressure under there to be raising this mountain.
And as far as simultaneous eruptions - weren't there a lot of major caldera eruptions in Kamchatka about 40,000-42,000 years ago?
So, if a large amount of sulfur dioxide has been released, can we expect cooling in the Northern Hemisphere? I recall that Pinatubo resulted in measurable cooling due to the SO2 effects.
