Eruptions

Archives for May, 2008

Ubinas, Peru

There are, indeed, other volcanoes erupting right now worldwide other than Chaiten. Of course, when you have an eruption like Chaiten going on, it is hard to pay attention to other eruptions. Ubinas, Peru Ubinas, in Peru, has been having intermittent ash eruptions for the past few months, depositing ash on the surround communities. Apparently…

Chaiten Eruption, Day 7

Another day, another development at Chaiten. Military stationed near the volcano helping with evacuations reported “booming noises” and saw incandescent blocks getting hurled from the vent area. This suggests that lava is at the surface and potentially that the edifice itself is beginning to crack/strain from the loss of material from the eruption. Remember, when you erupt…

Air travel in Patagonia

The eruption at Chaiten has now begun to have widescale effects on the region of Patagonia, beyond the ashfall. Air travel has been disrupted due to the amount of ash in the air. It is well-documented that ash posed a significant hazard to aircraft, so this seems like a wise move on the parts of…

One more Chaiten Image

NASA captured this great image of the ash plume from Chaiten, which has reached 15-km into the atmosphere. Following this eruption, I’m sure there will be a lot of work into why no one had any clue an eruption of this magnitude was about to occur.

Chaiten gains force

Well, this is getting rather harrowing. Volcan Chaiten, the Chilean volcano that sprung back to life last Friday after anywhere between 2,000 to 7,000 of quiet, is apparently erupting lava along with ash now. Sounds like its a good rhyolite/rhyodacite lava based on the description: “very small and very thick and as such was moving…

Kilauea Eruptions 2008

For those of you who have missed it, Halemaumau Crater at Kilauea (Hawai’i, USA) have been experiencing new eruptions – some of them explosive – for the last couple months. These are the first eruptions at Halemaumau since the 1980s and the first explosive eruptions at Kilauea since the 1920s. Much of the area around…

Chaiten Images

Monsters and Critics has some truly fabulous images of the ongoing eruption at Chaiten in Chile. The pictures of the extent of ash fall are quite remarkable. It is hard to tell exactly how deep the ash is or how far from the vent these pictures were taken, but one can imagine that if a…

Chaiten Eruption Update 2

Update 5/4/08: Looks like there is now officially a deathtoll for Chaiten, as an elderly woman died during the evacuations. The volcanoes continues to spew ash and I wouldn’t be surprised if it did so for at least a few more days. There have also been reports of a sharp increase in earthquakes in the area since the eruption.…

Chaiten Eruption Update

Update 5/3/08: SERNAGEOMIN (the Chilean Geologic Survey) is now concerned that the eruption of Chaiten may be a the precursor of a larger eruption, mostly owing to the long (~9,000 year?) repose time. This could be the beginnings of a southern Andean Pinatubo. The towns around Chaiten are more or less deserted now as the volcano continues…

Nevado del Huila

I’ve been following these rumblings for the last few months, but it looks like Colombia’s Nevado del Huila is ramping into a new cycle of eruptions. Huila lives in the shadow of its more famous brethren Nevado del Ruiz and Galeras, both of which have had recent and tragic eruptions. Huila is not believed to…
