Monday Musings

Some brief notes before I dive headlong into the exciting world of faculty orientation! A small steam plume coming from Turrialba in Costa Rica. Photo taken in August 2007. There are some preliminary reports of the state of wildlife (and everything) around Kasatochi Island in the Aleutians from the US F&W and USGS team that…

Monday Musings

I knew that the minute I said I’d be back to a “regular” posting schedule that I would fail miserably, so maybe the less said, the better. Cerro Galan caldera in Argentina (taken from space). Thanks to all the readers who have been avidly discussing a number of fascinating topics over the weekend. I have…

Monday Musings

Does anyone else feel like this has been a rather quiet summer, volcano-wise? Maybe I’ve been too preoccupied by my move to Ohio, but I feel like beyond a few relatively minor events (Shiveluch comes to mind), the volcano news has been pretty slow compared to the spring of this year. Go figure. The sulfur…

Is something up at Shishaldin?

Shishaldin volcano in Alaska. Yesterday I mentioned in the SI/USGS Weekly Report update that things appear to be afoot at Shishaldin in the Aleutians. Well, I checked the Shishaldin webicorder today and indeed, [SPECULATION] something seems suspect. Now, the increasing signal might be wholly unrelated to any magmatic activity, but it is interesting to see…

Your weekly dose of volcanism from the USGS/Smithsonian Global Volcanism Program. Highlights (not counting Mayon), include: The activity at Mando Hararo in Ethiopia appears to be a fissure eruption. Ground observations saw a 4-5 kilometers / ~2.5-3 mile fissure with new predominantly ‘a’a lava flows that were 2-3 m thick … the fissure was lined…

Tuesday Tidbits

Anak Krakatau erupting as seen from Rataka Island. Image taken by Marco Fulle of Stromboli Online. I frequent the Astronomy Picture of the Day website run by NASA on a daily basis. Yet somehow today I didn’t check the site until well into the evening and was greeted by one of the best astronomy-volcano images…

Friday Flotsam

Another fun weekend for me analyzing zircon on the SHRIMP-RG at Stanford University! I really know how to live it up during the summer. Some news bits: The 2009 dome at Redoubt in Alaska steaming on July 2, 2009. Image taken by Cyrus Read, courtesy of USGS/AVO In another sign that Redoubt’s 2009 eruption might…

Redoubt steaming in early 2009. Image courtesy of Calvin Hall. It has been a while since we spoke of Redoubt, but now it seems the reason why might be that the eruption is ending. AVO lowered the Alert Level at Redoubt to Yellow from Orange, indicating that they believe the volcano is less likely to…

Friday Flotsam

The Q&A post will be coming over the weekend (there’s still time to send me a question!) Icy cold volcanoes (well, geysers) on Enceladus, a moon of Saturn. In the meantime, here are a few quick hits: Mt. Cleveland in the Aleutians had a small eruption. The plume was only ~15,000 feet / ~3 km.…

Tuesday Tidbits

A few quick news bits … and thanks for the questions so far. Keep ‘em coming! Tungurahua, Ecuador erupting in 2006. Ash fall from Tungurahua (in spanish) in Ecuador is affecting the farm towns around the volcano. Farmers in Manzano, a village nearby, fear the ash is significant enough to damage their crops. The volcano…
