Even the SI/USGS Weekly Volcano Report seems a little light — welcome to the dog days of summer!

A sharp increase in sulfur dioxide output was noted at Mayon in the Philippines…

Your volcano news! Thanks, as always, to the USGS/SI Global Volcanism Program. Highlights include: The alert level at Sakurajima was raised from 2 to 3 by the Japanese Meteorological Agency. This was due to the increasing frequency of explosions at the volcano, some of which produced ash plumes up to 1.8-2.7 km / 6-9,000 feet.…

These volcanoes are defined by IAVCEI – the International Association of Volcanology and the Chemistry of the Earth’s…

I am back from the ion microprobe lab at Stanford after a few days of data collection, so I’ll be trying to get back on posting schedule here at Eruptions. UPDATE 3/10/2009 12:45PM: Here is a little (and I mean a little) more information, mostly adding that the local residents have been given a “warning”…

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…
