hmm,usually it takes a few mintues for a report to come out to their website.

Earthquakes an hour north of Chaiten.

Interesting delay in reporting by USGS.

By way of the ‘Volcanism Blog’ a story on Toba’s last eruption:

Just Monday a 5.8 earthquake occurred at its location. All right, I’m reaching.

here’s a very interesting report on Bloomberg about the man who owns this volcano. Yes, that’s right, owns. He’s Douglas Tompkins, the founder of North Face, Inc.

So his company can be sued for damages?

“It has to penetrate the upper TROPOSPHERE level before it can be carried around the world”

SERNAGEOMIN: The column exceeded 100K ft on four brief occasions prior to 5/12 and had ejected 2km^3 for a VEI of 5, but only some 10^3 tons of SO2.

The injection of ash and SO2 into the ‘stratosphere’ would have a cooling effect were the eruption at lower latitude. The one caveat here is the jet stream overlies Chaiten at this time effectively distributing the ash.

Ok here is more on the volcano:

Chaiten Volcano Summary:

On Friday, May 2, 2008, Chaiten Volcano in southeastern Chile erupted for the first time since about 7400 BC. Its initial eruption produced a plume of volcanic ash and steam that rose nearly 17 kilometers high. Winds carried the plume east, over the Andes Mountains and into Argentina. The plume then drifted out over the over the Atlantic Ocean. It was visible on satellite images for hundreds of kilometers over the Atlantic.

This is a fantastic website covering the eruption in detail.

That is interesting.

However I fail to see the effect go beyond the local region because the eruptive plume does not appear to be going high enough to get spread far and wide.It has to penetrate the upper TROPOSPHERE level before it can be carried around the world.

Can anyone shed more information about it?

I’ve got a funny feeling that this thing is emptying 9000 years of buildup, and when it’s empty and the cauldera collapses…. Krakatau time….

If this keeps up the Chaitén volcano may end up having a bigger carbon footprint than Madonna and Al Gore combined.

FWIIW, I don’t think the final eruptive event is imminent. Not enough earthquakes for one thing.

And if you want to scare yourself with how bad it could be, read this.

Thanks Brian D. for the links. The loops much more clearly show how extensive the ash distributions is. I was also able to get more out of the Terra image after seeing the loops.

In answer to Beano’s question about the link between the two volcanoes I would venture a guess that there is a reasonable probability that they both could share a magma source at depth. I doubt they would share a magma chamber closer to the surface though.

I noted in an earlier post that the terrain surrounding Chaiten did not appear to be that which typically surrounds strato volcanoes. My guess then was that perhaps Chaiten was a newer eruptive center.
