More Chilean rumblings

If Chaiten, Llaima and Puyehue weren’t enough, the Chilean Regional Emergency Office is placing seismometers on Peteroa volcano after its shown signs of increasing activity. The volcano is located out on the border with Chile and Argentina and has a number of glaciers that start from the edifice. Looking at the eruptive history of Peteroa,…

Your Daily Chaiten Report

A bit busy today, so to borrow from the newest USGS/SI Volcanism Report: On 12 May, the plume rose to an altitude of 8 km (26,200 ft) a.s.l. During an overflight conducted by SERNAGEOMIN, four more plumes of a similar altitude were generated by explosions and drifted NE. Several hectares of burned vegetation, likely from…

Beginning of the ? for Chaiten

I just read a report that the ash column at Chaiten is beginning to collapse. The SERNAGEOMIN says that the ash column is only 4.5 km tall now, as opposed to the 20 km it had reached earlier. Still, there are not reports of pyroclastic flows, but that could be a matter of hours or…

Ruapehu Update

Looks like we should expect an eruption at Ruapehu (New Zealand) any time now. Tremors are ongoing, along with increased volcanic gas emissions (specifically SO2 here) and warmer temperatures in Ruapehu’s crater lake. All of these ingredients point to a higher probability of eruption. However, with all that begin said, the Alert Level at Ruapehu remains at…

Yellow Alert at Puyehue

While I was looking at the gallery of Chaiten photos, I noticed another headline (in spanish) saying that the SERNAGEOMIN has issued a yellow alert for potential activity at Puyehue. Now, the “article” doesn’t offer much besides pictures and maps, but apparently there has been an increase in seismic activity in the vicinity of the volcano.…

Chaiten Photo Gallery

Here is a gallery of some ridiculously cool photos from the Chaiten eruption …  

Chaiten to bury Chaiten

I’ve been trying to keep up with the Chaiten eruption in Chile, but the news is just beginning to sound like a broken record: eruption continues, ash falls, don’t know much else. However, it does sound like Chile is being realistic about people’s chances of moving back to the town of Chaiten – 10 km…

Mt. Etna at it again

Etna, one of Italy’s (and the world’s) most active volcanoes, has started erupting again. Saturday night the volcano erupted lava flows, although that is pretty much all the details in the article. The last series of major eruptions at Etna were last fall, but the volcano never tends to stay quiet for long. For those…

On my random speculations

Before we get too far, I wanted to make sure that folks understand that I’m just making educated conjectures on the nature of the eruptions I read about and by no means do I have any extra insight over those scientists on the ground at the eruption. I have a very limited set of data to…

This marks a full week of eruption at Chaiten and the volcano shows no signs of abating. You have to feel for Luis Lara. He is apparently the pointman for the SERNAGEOMIN in regards to this eruption and really, I think its anybody’s guess what might happen next. Heck, we haven’t seen many eruptions of…
