I'll be brief (as I'm in the middle of moving), but I did see a report that activity at Chaiten is increasing yet again. This seems like the operating mode for this volcano, with a waxing and waning of intensity, since the volcano started erupting on May 2. The latest report indicates renewed ash emissions producing an ash column that reaches ~20,000 feet (4,000 meters), with ash falling on nearby areas. There is also mention of some increased seismic activity at the Chilean caldera. The picture above shows the extent of the mobilized ash and volcanic debris that has wiped out much of the town of Chaiten (taken from the space station at the end of May).

It is hard to believe that we are less than one month away from one-year anniversary of the beginning of the eruption at Chaiten (and with it, the one-year anniversary of this blog!) The volcano in southern Chile…
UPDATE 2/19/2009 9:45 AM: Well, it seems that my hunch was at least partially right. Reuters (and Paula Narvaez, special envoy to the Chilean president) is calling the eruption as result of "what appeared to be a partial collapse of its cone."Â So, we might have seen the oversteepening of the dome…
Although the mainstream media seems to have lost interest in the Chaiten eruption beyond the "human interest" (or should I say "salmon interest") aspect of the eruption, there is still a lot going on at the volcano. The SERNAGEOMIN recently released this excellent photo of the erupting caldera:…
Actually, no the volcanoes aren't from space, but pictures of the volcanoes were taken from space. The NASA Earth Observatory has posted three more gems of volcanic activity taken by one of the fleet of earth imagers in orbit:

Also, I recent heard that the Chilean government has now decided that they will not rebuild the town Chaiten because the lahar threat is expected to continue for a long time.
My mate and I were just talking over this problem, truly continually trying to prove me entirely wrong! I am about to present her this write-up and rub it in a bit!
