Chaiten Redux

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.” So, we might have seen the oversteepening of the dome growing in the Chaiten…

Japan planning ahead … way ahead

I found this little press release that doesn’t have a huge amount of information, but is interesting nevertheless. The Coordinating Committee for Prediction of Volcanic Eruptions of Japan (nice name) is putting seven volcanoes on “24/7″ monitoring. That sounds like we might see a lot of eruptions in Japan soon … except that their rationale was…

Redoubt Mini-update for 2/18/2009

Not much to add to the Redoubt Watch this week. The volcano continuing to experience increased seismicity and AVO is watching it closely. Sounds like we’ll be doing the same for the time being.

Galeras erupts

UPDATE 2/15/2009 20:30 PM: Marta Calvache of INGEOMINAS says that seismicity has all but stopped at Galeras after the eruption Saturday night, however the area will be kept on alert for more potential activity. However, even with the eruption, apparently there are very few people in the evacuation centers – never a good sign if…

Redoubt Mini-update for 2/13/2009

We’ve now had three weeks of waiting for Redoubt, and all we have to show for it is steam, seismicity and lots and lots of press. As of today, Redoubt continues with the same: elevated seismicity, constant monitoring, think it will erupt. Current status from AVO: Redoubt Volcano has not erupted. Elevated seismicity is continuing,…

Eruptions Mailbag #2

I get a fairly steady stream of emails from Eruptions readers, some of which are very worth a post, but sometimes it takes me a while to get around to posting. This is my second attempt to catch up on these mailbag emails. Remember, feel free to email me questions or comments whether you want. Reader…

Redoubt from space

The NASA Earth Observatory website posted this great image of Redoubt taken from Landsat images in 2000. You can see a few neat things. The main thing I notice is that the Drift River Oil Terminal is in about the worst place you could put an oil terminal near a volcano like Redoubt. All the…

Redoubt Mini-update for 2/10/2009

Is the volcano just toying with us? After yesterday’s steam plume (woo.), Redoubt was relatively normal today, albeit still at the heightened state of readiness. However, the steam plume has waned today compared to yesterday. Now, whether this is actually a signal that the magma is not rising up into the volcano as rapidly as…

Redoubt Mini-update for 2/9/2009

Jury duty is done, so here is a little update. Redoubt is puffing away, producing a more prominent steam plume than it has over the last week (but that may be more weather-related than magma-related.) Beyond that, the volcanic gases keep coming and the earthquakes keep coming.

Redoubt Mini-update for 2/8/2009

Guess what? Still rumbling, still steaming, but still no eruption. I’ll put money on the idea that Redoubt will erupt tomorrow, when I have jury duty.
