Redoubt update for 3/17/2009

Now that Redoubt has decided that Yellow/Advisory is not to its likely and has returned to an Orange/Watch status, I’ll continue bringing new updates of the volcano has events unfold. And nothing much has unfolded since the phreatic explosion that occurred on Sunday. The current state of the volcano, according to AVO, is minor seismic…

Extremophiles, Volcanoes and You

Folks have been suggesting that life on Earth started near volcanic vents for a long time now (and of course, some people don’t buy it). Whether or not life sprung forth near hydrothermal vents, undersea black smokers or from the head of Zeus, it doesn’t really change the fact that we find organisms living in…

Count this as your mini-update for Redoubt, with the news being no news. Even AVO seems a little bored with Redoubt lately (not to say they aren’t watching it as vigilantly as ever) as their last three updates have been exactly the same: Redoubt volcano has not erupted. Seismicity is low, but above background levels…

Redoubt Mini-mini-update for 2/28/2009

As there has been a lot of chatter about the goings-on at Redoubt, I thought I’d post the latest AVO update (3:35 PM): Redoubt volcano has not erupted. Seismicity is dominated by small discrete earthquakes and tremor remains at the diminished levels of the past two days. Webcam images are now clear and show no…

Redoubt Mini-update for 2/26/2009

The Redoubt watch is now been going for well over a month and this is how quickly things can change when monitoring volcanoes. The headline in my volcano RSS, when I saw it said: “Redoubt quiets after weeks of activity, though eruption still possible” By the time I clicked on the link, the headline for…

Redoubt Mini-update for 2/24/2009

Not much new to report with Redoubt except that folks in Alaska are getting, well, a little punchy. AVO currently reports (7:12 AM): Volcanic tremor and occasional discrete earthquakes continue at Redoubt. Since 00:00 local time on 2/24, tremor amplitude at nearby stations has gradually increased, and the number of small earthquakes on nearby stations…

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,…
