On another thread, I saw this post:
On Saturday, April 12 (19,45 hrs), a huge fireball swept down over the Chacarilla Hills that encircle Santiago, Chile's capital city. Researchers of these phenomena that witnessed the event were able to take photos, and promptly e-mail them to diverse forums. Then, I wonder...could this be related to the Chaitén eruption that began on May 2?
Reports from Chile indicate that the very same day a second volcano, the Mochimahuida, some 40 kilometers to the south of Chaitén, began erupting after having remained dormant for almost two centuries. The Chaitén had last erupted in 7420 B.C., or 9,370 years ago, according to the Chilean National Geological Survey.

Things are really going crazy in that region. If the volcano does collapse I hope it is captured on camera. But I suspect it will happen at night like most great hurricane landfalls. It is like we just aren't entitled to good video :-)

Chile town closed for three months after volcano
| Quote From Source: | SANTIAGO, May 14 (Reuters) - The government on Wednesday declared the evacuated Chilean town of Chaiten off-limits for three months until it is no longer threatened by a cloud of hot ash from an erupting volcano.
The Chaiten volcano, six miles (10 km) from the town that had been home to 4,500 people, started erupting on May 2 for the first time in thousands of years, spewing ash, gas and molten rock into the air.
The column of debris, kept aloft by the pressure of constant eruptions, could collapse and smother Chaiten.

Dang! That thing is still erupting? The longer it erupts the more likely I think it is that this volcano collapses in the end.

what doom is next?
volcano - check
cyclone - check
quake - check
I'm thinkin heat wave...
or maybe giant solar flare |

This story just posted about 2 hours ago states there is concern about this volcano. Here are a couple of quotes from the Reuters report.
| Quote From Source: |
Chile's Chaiten volcano groaned, rumbled and shuddered on Thursday, raising new concerns among authorities, as lightning bolts pierced the huge clouds of hot ash hovering ominously above its crater.

"There's been additional volcanic activity that we're really worried about," regional governor Sergio Galilea told reporters.
The Chaiten volcano, 760 miles (1,220 km) south of the capital Santiago, started erupting on May 2 for the first time in thousands of years, spewing ash, gas and molten rock into the air.

I want to know what those rumblings are and what concerns they ended up raising. I think the concern is an explosion and collapse of the volcano itself.

Here is the latest update from Seach on the Chaiten volcano.
| Quote From Source: |
Continuous eruptions are occurring at Chaitén volcano in Chile. The airfield at Chaitén town has been covered by ash and water, and is currently not able to be used. Ash and pumice is floating northwards along the Chile coast. The bay near Chaitén contains run-off from rivers with a milky-green colour. A large amount of sediment has blocked river channels, and lahars will continue to overflow river edges. Over the past two days there has been a marked change in seismic activity at the volcano. Earthquake swarms indicate fracturing of the main conduit, and possible ascent of magma towards the surface. Increasing pressure from magma is creating a potential explosion hazard, and collapse of the dome, generating

This eruption has been going on for two weeks now. It is pretty big. Now it looks like something even bigger is likely coming. If the dome collapses god only knows what kind of hell it will unleash. Just imagine opening a gift at Christmas. You remove the paper and you find a generic box. There is that anticipation as you remove the lid. What will be inside that box? Will it be a socks and a scarf or maybe the latest and greatest universal remote.
If the dome collapses I think we will find out just how much was in the magma chamber. After being dormant for 9,000 years the results may not be good.
You guys should check out this forum on a somewhat regular basis until the eruption comes to an end. Also visit Seach's site as well.

what worries me is the type of volcano this is. Same as Yellowstone and Lake Taupo.
Those scientists who say this volcano won't have an impact on the northern hemisphere's climate are going to be surprised...that is, if the volcano has a massive eruption (like Lake Taupo).
"The rain it raineth every day, and every night also -- week in and week out, from the rising of the sun to the going down of the same, there is nothing but rain, rain, rain, 'The windows of heaven are opened up.' Pluvius, grieved at some earth-giving wrong, weeps as if he never would dry up." - Overland Press (Olympia, WA), December 1861 |

Identifying The Magma Chamber
I've been trying to find any clues as to the size of the magma chamber under Chaiten. A clue may have been found. Look at this link....
www.seablogger.com
Lets assume those 5 big quakes marked the outline of the magma chamber. You would be looking at an oblong chamber that is about 45km from one end to another and 30km from one side to another. Give or take a couple of km in length of width. Basically it would look like a stretched out oval. Using what little I remember from geometry I split the thing in half and calculated the area of a parabola. Each half would be 230 km^2. So total surface area would be 460 km^2. Calculating the volume would be a nightmare.
Looking at the number for Yellowstone they have it at 60km x 40km and 10km from top to bottom of the chamber. If a cube that would be 24,000 km^3. But it isn't. The USGS estimates the capacity at 15,000 km^3 or 62.5% of the cubed volume. Since the dimensions above were similar in shape I am going to apply their percentage to Chaiten. But since the chamber is smaller I am going to assume from top to bottom it is smaller as well. This calculation assumes 5km instead of 10km. So 45km x 30km x 5km * .625 = 4,219 km^3.
Of course this makes many assumptions and should in no way be looked at as fact. Just food for thought. If those quakes indeed mark the outline of the magma chamber when you can look at 4,219 km^3 as a pretty accurate representation of the chamber. You don't have to follow volcanoes very long to understand what that implies.

say we had a lake taupo sized eruption down there...how long would it take to change climate up in the states?
we have been talking about how next winter is going to be bad but with an eruption like some in this forum r suggesting, we will be worrying about summers also. |

With this being in the southern hemisphere I wouldn't worry too much in the northern hemisphere.

Even with the size of the chamber???
That's like saying if Yellowstone blew it wouldn't effect Australia in the year to come.

I just have to point out here, that Yellowstone last Erupted with only 10% of that capacity. So even if Chaiten goes big, along the same lines it would only manage a VEI 7, which is still huge, but doesn't quite get the "Super" title. Of course the structure of the areas is likely completely different as Chaiten is probably subduction fed rather than hotspot fed so it could be more explosive. |

I just don't see how anything VEI 6 or bigger does not effect the whole planet in one way or another.

Here is the latest from Seach.
| Quote From Source: |
Eruptions continue at Chaitén volcano in Chile. A dome is forming in the active crater, with sporadic explosions and pyroclastic flows. Seismic activity consists of swarm of hybrid events which indicates movement of magmatic fluids and gases, low and high frequency earthquakes. The alert level remains at the highest rating, RED.
