Redoubt Mini-update for 2/6/09

Just to keep us appraised of the situation at ever-steaming-and-shaking Redoubt: From AVO (2/6/2009 11:05 AM) Unrest at Redoubt Volcano continues.  After the tremor episodes of yesterday, seismic activity has remained slightly elevated relative to the last few days.  The volcano has not erupted. That is about it. A few quick hits about Redoubt (as…

For those of you interested in what happens in the realm of submarine volcanism, I can pass on some tidbits I’ve gotten about NW-Rota 1, a submarine volcano in the Mariana Islands (see bathymetry above). Dr. Ed Kohut (Petrogenex), a friend of mine from my days at Oregon State Univ., is currently on a JAMSTEC research cruise…

Redoubt Mini-update

For all you Redoubt vigil holders… According to AVO at ~12:30 (2/5/09): Starting at 11:18 AKST (20:18 UTC), a burst of more intense seismic tremor occurred. This episode lasted for about 4 minutes and was the most most energetic since January 30. Radar and pilot observations confirm our analysis that no eruption occurred.

Eruption soon at Huila?

Bored with waiting for Redoubt to erupt? Well, Nevado del Huila in Colombia looks like it is also on the eruption watch list. A fly-over of Huila performed by Colombian officials (unclear from the article if it was done by National Emergency Management or INGEOMINAS) revealed a large lava dome growing in the crater, suggesting…

A week ago, if you asked around, I’m sure most people would have thought Redoubt would have erupted by now considering all the seismicity and melting that was seen at the end of last week. However, volcanology is not an exact science, and here we are continuing to watch Redoubt tease us with signs of…

Redoubt continues to keep us waiting

Redoubt (above) is definitely taking its time. After catching everyone’s attention last week with seismic activity, melting of its snow cap and increased gas emissions, the volcano is still, well, doing all those things, but not erupting. AVO’s update are beginning to sound like a broken record: “(2/3/09 04:10) Unrest at Redoubt Volcano is continuing…

Mt. Asama near Tokyo did, in fact, erupt within the “two day” window predicted by the Meteorological Agency of Japan. The reports this morning put the ash column at ~2,000 meters (~6-7,000 feet), so relatively small, but big enough to dust parts of Tokyo (~145 km away) with ash. No evacuations are planned for the…

Alert level raised at Asama in Japan

UPDATE 2/1/09 5:02 PM Pacific: Indeed, Asama did erupt today. The eruption was relatively small, throwing ballistic clasts up to 1 kilometer from the vent and ash into the outskirts of Tokyo. Redoubt in Alaska has dominated the volcano news as of late, but it is clearly not the only volcano on Earth that is…
