And personally I can't think of many worse ways to die, either.
Just out of interest, has any news source got an estimate of total volume erupted? It's been going on for long enough for a fairly big volume by now. |

some great pics comparing st helens and this volcano r here:
http://volcanism.wordpress.com/
i know the site has been posted already but the pics r new. caldera sizes r just about the same size.
also, the site talks about how there were some new earthquakes 88 km north of the volcano. it was 22.4 km deep. a 5.4...they say that makes it tectonic but another shallower one was reported at 5.0 and at a depth of 9.8 km. what makes this a bit interesting was that these occured near or under 3 or 4 volcanoes with no historical evidence of eruption. |

It has been a month now and the eruption of Chaiten continues.

yeah, but its certainly much smaller these days than at the beginning. does anyone remember if pinatubo had small eruptions afterwards for this long? i also wonder if anyone has found out how much sulfur dioxide has spewed out now at this point. |

I disagree. You can never be certain with volcanoes...and earthquakes.
"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 |

Just thought I'd update that Chaiten is still erupting. It was looking as if briefly the end of the eruption was near but since then two new vents have opened up and seismic activity has increased.

Seems the situation at Chaiten is getting worse.
| Quote From Source: |
The most troubling to me is this part of the report: [The military flyover] spotted two new craters. Officials said they saw bursts of gas coming from different areas around the base of the volcano. This suggests that there is enough pressure under the volcano to start opening new vents. Whether or not this leads to the formation of a ring fracture - the series of fractures around edge of a caldera that facilitate collapse - is pure speculation, but at the very least, this is a new stage of activity at Chaiten.

Oh, this doesn't sound good ... to quote a movie line, "I have a bad feeling about this". Here is more news ...
| Quote From Source: | The eruption of southern Chile's Chaitén Volcano intensified on Friday, inflicting a new round of damage on nearby communities and slowing government-led relief efforts. Local officials said that volcanic activity could be at one of its highest levels since Chaitén began erupting more than one month ago.
“Even though the volcano has remained active since its initial explosion, today we can definitely said that the situation has worsened,” said Chilean Defense Minister José Gońi.

last thing i heard though, granted it was last month, was that this had hardly put out any sulfur dioxide during the initial eruption. now, i havent seen any numbers since but i think it wont have too big affect on the winter. |

Well, even if the Volcano doesn't noticably affect the climate, it still should be an interesting winter, w/ the Sun being so quite. |

This is getting really bad. The following site has done a great job of covering Chaiten since day one. It is one of the few places you can find translated stories. Not sure who does the translating but it is good info.
http://www.seablogger.com/?cat=22
| Quote From Source: |
A larger survey of dome building shows a partially comparable event, at Mount Lamington in Papua New Guinea, during a 1951 eruption. A violent explosive episode began on January 21. Dome-building commenced four days later. It proceeded at a rate of about 18 cubic meters per second through March 5, when a paroxysmal eruption blew most of the new dome away. After that climactic event, dome building resumed and continued for several more months.
At Chaitén the first stage of dome-building was estimated at 37 cubic meters per second. It has now accelerated past fifty. No wonder the photos are so striking. This is an event outside historic parameters.

And the daily summary ends with this....
| Quote From Source: |
At the least, one must wonder about the mechanical stability of the huge, teetering dome. Collapse could release internal pressure and trigger an explosive eruption that would destroy the edifice. It is also possible that rapid evacuation of the magma chamber could lead to a larger collapse of the entire caldera floor. This would probably induce an eruption with serious global consequences. We can only watch and wait.

I can't thank this person enough for the great coverage of this eruption. Without the link I posted above I am not sure were we'd get a good flow of news in English.
This is some serious stuff and it is getting no coverage in the U.S. news. I hope someone picks this up and we start getting even more details.

Here is the latest from Fresh Bilge.
| Quote From Source: |
I received the latest information on Chaitén activity overnight. Instruments recorded a doubling in volcano-tectonic earthquakes during the last couple of days, and increases in magnitude as well. Small quakes reached 115/day, with 25-30 greater than magnitude 2.0. Epicenters are under the west and southwest part of the caldera (closer to the town than before). They are said to be in the lower part of the upper volcanic system, whatever that is thought to mean. Yet there is no harmonic tremor, which would indicate movement of magma. The VT signals are characteristic of rock-breaking, but there is no indication of what is breaking them. Sernageomin is evidently puzzled by the activity, and declines to draw any conclusion.

Source: Update 28
Check out the rest of the author's comments for the full update. I've never followed a volcanic eruption as closely as this one so I have nothing to compare it to. I don't know how unusual any of this activity is. The author seems to have a pretty good grasp of this material. So check the site often.
Again here is the main feed.

Tambora took 3 years to completely blow it's wad. IT started reupting is 1812 and came unhinged in 1815. |

This is one of the Chaitén cams. It is still erupting.

The only reference they make to the pre-1815 monterous eruption on Wikipedia is:

Kinda sounds like Chaiten. It has rumbled and generated a dark cloud.... |
