The volcano, 800 miles south of the capital Santiago, had not erupted for more than 450 years and was considered dormant.
But it is now belching enormous clouds of thick ash that have drifted across a large area in both Chile and the Argentine province of Chubut, where an airport was forced to close.

This is a quote from the story in the first post. After 450 years of being dormant this volcano would have quite a bit of material to eject. If you look at the picture in the link you'll see it was quite an impressive eruption. Any guesses as to the height of the ash cloud? I'm thinking 30,000 to 40,000 feet.

Here is more information. It seems to conflict with information in the first story in regards to dormancy.
| Quote From Source: |
The Chaiten volcano has "probably been dormant for about 9,000 or 10,000 years but that's not unusual," said Charles Stern, a professor of volcanology at the University of Colorado who specializes in Andes volcanoes.

But the article also states....
| Quote From Source: |
The eruptions shot ash up to 1,600 feet (500 meters) into the air, said Santos Alvarez, an official from the town of Ubinas.

That information is obviously extremely inaccurate.

A story by the Associated Press states...
| Quote From Source: |
The Chaiten volcano spewed light ash on a nearly deserted village Saturday, two days after its first eruption in thousands of years.

Also in the article it states...
| Quote From Source: |
the volcano belched fat smoke plumes that at times rose as high as 12 miles (20 kilometers) into the air, the government's Emergency Bureau said

That seems more accurate based on the photo in the link in the first post of the thread. In the picture the ash cloud seems to hit a lid much like severe storms do when they hit about 60,000 feet. And 12 miles would be consistent with that. Now getting the ash that high into the atmosphere will keep it aloft for quite some time. Is this eruption big enough to have an impact on the climate. I'm interested in seeing how long this drags out. Or is it done already?

I've seen 10miles reported (50,000 ft) on a blog, but cannot confirm yet.
However high it is, it most certainly is more than 1600 ft:

Yeah that is certainly more than 1600 ft high. I could piss 1600 feet high with a hard-on and I'm pretty sure that volcano packs a little more punch than I do.
They should take the warning labels off of everything and let stupidity sort itself out.

it is in a remote area so at first they thought it was another volcano which might clear up the whole 450 yr thing. |

Here is a way to find out who is a Google expert. What was the last volcano to erupt that hadn't erupted before in thousands of years? They say maybe 9,000 or 10,000. But lets just go back 5,000 years. What volcano was it and how big was the eruption?
First person to find a volcano that has erupted since 1990 but previously hadn't erupted for 5,000 years or longer gets 5,000 points.

If you are talking about Soufrière Hills then not quite.
www.volcano.si.edu
Previous event was approximately 1630.

Tha answer is: There haven't been any eruptions of 5000 year dormant volcanos since 1990. Pinitubo had been dormant for 450 years. St. Helens in 1980 had been dormant for 123 years. |

the caldera is 3.5 km wide according to this. . .

By comparison, Pinatubo is 2.5 km wide

A cataclysmic blast is possible
| Quote From Source: | Scientists in Chile are now frantically collecting data in an attempt to measure how much magma has built up under the volcano.
"This could be an isolated incident or the start of quite a long period of rumbling," said Prof Clive Oppenhiemer, a volcanologist at Cambridge University.
Chaiten is a caldera volcano, which can explode in a cataclysmic eruption, emptying the magma chamber and causing the dome and surrounding land to collapse into the void beneath.

just throw this in with the negative pdo and a quiet sun...things could be getting real interesting soon.
and according to volcanolive.com, the past eruptions on Soufrière Hills were the only ones in written history. there have been a few failed eruptions but no actual true eruptions.

You mean besides this one right?
The Chaiten volcano last erupted more than 9,000 years ago

SANTORINI ERUPTION (~1630 BC)
| Quote From Source: | The islands of Santorini did not form from a single event, but rather from a variety of eruptions over a long period of time. Geologic studies indicate that at least 12 eruptive phases have occurred over the last one million years. The late Bronze Age event was a Plinian eruption of epic proportions, with an estimated Volcanic Explosivity Index (VEI) of 6.9. The immensity of this eruption is equaled or surpassed by only seven other terrestrial eruptions in the past four millennia.

The eruption of ash was certainly powerful. With the cloud reaching nearly 60,000 feet into the atmosphere there was obviously some force behind it.
So we are dealing with a volcano that was dormant long enough to potentially unleash a climate changing eruption at the same time we've entered a cool PDO phase and are in the middle of a solar minimum.
This eruption will be bad if it only reaches the level of Pinatubo.
Perhaps the only saving grace could be that this mountain is located in the southern hemisphere.
