All the news to start the week: Galeras with a grey ash-and-steam plume behind Pasto, Colombia. Well, after my article on Friday about Colombian volcanoes, Galeras must have decided it was left out. The volcano has been placed back at alert level Orange/II (eruption in days to weeks). An increase in seismicity and sulfur dioxide…

I’ll be giving a talk this afternoon here at Denison on rhyolite generation, so I might be a little brief this morning. Undated image of Mayon in the Philippines. The province of Albay in the Philippines is on alert for both a typhoon and a volcano (that country seems to be hit with that

I did an excellent job of forgetting my notes from GSA 2009, so no wrap up on the meeting until tomorrow, but we do have some new volcano news to digest: The crater of El Reventador in Ecuador in an undated photo. Ecuadorian officials have called for evacuations around El Reventador. The Ecuadorian Geophysics Institute…

Mayon has minor eruption

Mayon in the Philippines, taken in 2007 There has been a lot of waiting over the summer to see if Mayon in the Philippines was going to begin a new eruption sequence. This morning, the volcano had its first “eruption” since August 2008, producing a very small (~700 m / 2000 foot) ash-and-gas column that…

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…

Even the SI/USGS Weekly Volcano Report seems a little light — welcome to the dog days of summer! Highlights from this week’s report include: “Thunderous sounds”, incandescence and small plumes (hundreds of meters) with more frequent seismicity at Ibu in Indonesia. A sharp increase in sulfur dioxide output was noted at Mayon in the Philippines…

Friday Flotsam

Some of the articles you might have missed this week … A lava flow from Kilauea breaks local traffic laws in the Royal Gardens subdivision, Hawai’i The Mayon Watch continues in the Philippines. No eruption yet, but some of the local newspapers are printing stories talking about “odd animal behavior” and other local “myths” about…

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…

Mayon erupting in August 2004. The increasing unrest at Mayon in the Philippines has prompted National Disaster Coordinating Council (NDCC) to recommend the evacuation of over 75,000 people from around the volcano. This, however, will only happen if the activity at the volcano continues to increase. The volcano currently sits at Alert Level 2 (increasing…

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…
