Another tidbit from AGU…

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.

    The Smithsonian gives the height of the volcano at 6008 meters or 19,711 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.
