Redoubt Returns?

The most recent image on the AVO website of the dome at Redoubt, taken in November 2009. Image courtesy of AVO/USGS, by Cyrus Read. Not much information on this, but AVO just raised the alert status at Redoubt in Alaska to Yellow for the first time since late September. A series of small earthquakes were…

The big geology news right now is the M8 earthquake in American Samoa that generated a killer tsunami (which made it all the way to the Bay Area in California). Mammoth Mountain in California’s Long Valley region. In more benign, volcano-related news: The aviation alert level at Redoubt in the Alaska has been returned to…

Some brief tidbits for your Wednesday: The view of Mt. Saint Helens from the Johnston Ridge Observatory. There is a decent article about research being done at a dissected caldera system in the Italian Alps’ Sesia Valley. The caldera in question is the Permian in age (248-298 million years old) so don’t expect to find…

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…

A wrap up of the week’s volcanism, brought to you by Sally Kuhn Sennert and the USGS/SI Global Volcanism Program. Highlights, not including Sarychev Peak, Redoubt and Shiveluch (busy week in the north Pacific), include: A small ash cloud was spotted at Bagana in Papua New Guinea. The Tavurvur cone at Rabaul (PNG) continues to…

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…

Shiveluch volano in Russia. Just like last summer seemed like a busy time for the Aleutians (Cleveland, Okmok and Kasatochi), this summer could be dubbed the “summer of Kamchatka-Kurils” (alright, it isn’t that catchy, sorry). The biggest news was/is, of course, the sizeable eruption from Sarychev Peak in the Kuril Islands, but not to be…

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…

Your weekly dose of volcano news brought you by the Smithsonian Institute GVP and the USGS. This week’s highlights (not counting Sarychev Peak and Turrialba) include: 13,000 foot / 4 km ash plumes from Rinjani in Indonesia. This is part of the continuing eruption there. The alert level was lowered at Galeras, Colombia to “Orange”…
