Classes starting today, so I have to be brief: Unique twin ash plumes from Sinabung in Indonesia, erupting on August 29, 2010. Sinabung The Indonesian volcano continues to experience explosions, which one last night (well, last night here in Ohio) that prompted an ash advisory for aircraft up to 6,100 m / 20,000 feet, although…

A new Weekly Volcanic Activity Report from the Smithsonian and USGS Global Volcanism Program! Highlights from this week’s report include: Things are getting a little noisy in Colombia. I mentioned a few weeks ago about a possible explosion at Nevado del Ruiz. Now we have reports of increased seismicity under nearby Cerro Machín and ash…

Mt. Hood in Oregon, taken August 2008. Image by Erik Klemetti. Click on the image to see a larger version. Quick news! I’m not going to go into too much depth right now about the recent study published in Nature Geoscience on Mt. Hood in Oregon – I plan to talk about it more in…

Just a reminder, if you any questions for Sally Kuhn Sennert of the Smithsonian/USGS Global Volcanism Program – about the Weekly Report, about life at the GVP, about volcanoes – be sure to send them to me soon at . Now, on to this week’s update! Some highlights (not including Gorely): Lahars from Tungurahua in…

The latest news from the world of volcanoes, brought to us by the Global Volcanism Program, USGS and the Smithsonian Institution. They are also brought to us by Sally Kuhn Sennert – and if you have a question for her about her job at the GVP preparing the Weekly Volcanic Activity Report and all things…

News for Monday! Ngauruhoe in New Zealand, showing the dark lava flows of basaltic andesite on the slopes of the young volcanic cone. Image by Erik Klemetti, taken January 2009. A couple pieces of news from two Russian volcanoes on the Kamchatka Peninsula: (1) last week’s report of activity at Gorely appears to be semi-substantiated…

This week went fast, didn’t it? The Baekdu caldera along the North Korean/Chinese border. The NASA Earth Observatory have been giving us a steady diet of volcanic plumes over the last week, including PNG’s Ulawun, Russia’s Sarychev Peak (a very faint plume), both an ASTER and Terra image of the summit region at Kliuchevskoi and…

The latest update from the Smithsonian/USGS Global Volcanism Program! Highlights (not including Taal, Eyjafjallajökull and Bezymianny) include: Another thermal anomaly was spotted on an Kuril Island volcano – this one being Tiatia. The volcano has no seismic monitoring network, so the thermal anomaly is all that has been observed. Lava flows and strombolian explosions continue…

The NASA Earth Observatory has been dazzling us with images from the Eyjafjallajökull eruption for months – but they have been dazzling us with volcanoes images for years! Here are two more images for those of you who love seeing volcanoes from above: Cleveland, Alaska As I mentioned earlier this week, Cleveland volcano likely had…

Tungurahua in Ecuador erupting on May 31, 2010. Two volcanoes along the edge of the north Pacific had explosive eruptions over the weekend. We have some more details on both of the eruptions, so I’ll pass them on: Bezymianny KVERT is excited because they claim to have predicted the explosive eruption of Bezymianny almost to…
