eklemetti | February 17, 2010The rhyolite domes of Chaiten in Chile in an undated photo. Note how much of the previous Chaiten Caldera has already been filled by the new domes that started after Chaiten erupted in May 2008.
CNN International has a report that the National Emergency Office (ONEMI) in Chile has reinforced the "red alert" status of Chaiten (spanish). The volcano, which has been erupting since May 2008, had recently settled down to slow, but constant, dome growth. However, over the last 3 weeks, seismicity has been increasing at the rhyolite caldera, suggesting that we might be heading towards an upswing of…
eklemetti | February 16, 2010Not a lot of big news, but a lot of little news:

This might not be new, but Dr. Boris Behncke brought the new webcam at the rim of Chaiten in Chile to my attention. You get a birds-eye view of the growing dome from the edge of the caldera - pretty nifty view for a once-in-a-hundred-years sort of event.
The NASA Earth Observatory has posted a close-up of the Soufriere Hills imagethat I posted yesterday, showing the February 11 plume. The…

Eruptions reader Boris Behncke pointed out that things are afoot in the Halema`uma`u Crater at Kilauea. To steal his description: " the lava lake returned triumphantly to the active pit last night, and now it is filling virtually the entire field of theHalema'uma'u Overlook webcam." Sure enough, checking out the webcam this morning, the field of view is dominated by a lava lake - albeit somewhat crusted over by hardened basalt lava. You can compare the current image with one from…
eklemetti | October 30, 2009There has been news over the last few days of a number of volcanoes in Colombia, so I thought I'd try to gather it up here:
The steaming summit of Nevado del Huila in Colombia
Nevado del Huila has been ramping up its ash emissions, potentially pointing towards new eruptions from the crater dome. The NASA Earth Observatory posted a new image of the grey ash plume from the volcano poking its way up through the clouds. This plume made it all the way to ~11 km / 36,000 feet, so it definitely isn't insignificant. This comes after an increase in seismicity (up to 1,000 earthquakes in the last week…
eklemetti | September 29, 2009As fall descends on the northern hemisphere, spring starts in the southern. Luckily for us, it means that we get better views of the southern Andes in Chile ... which means the NASA EO could train one of the many "eyes in the sky" (specifically the EO-1) on Chaiten. The volcano is still erupting, going on 16 months, since it caught everyone off guard in May of 2008. As you can tell from the image (linked and below), Chaiten is slowly filling in the pre-2008 caldera with new rhyolite dome growth - you can see that the pre-2008 dome within the caldera (see the picture taken from the ISS in 2003…
