All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP!
Highlights (not include Manda Hararo, Kilauea and Mayon) include
- San Miguel in El Salvador has been experiencing increased seismicity. The last time the volcano erupted was in 2002.
- A pilot spotted a ~10,000 foot / 3 km ash plume emanating from Anak Krakatau in Indonesia.
- Another ash plume, this time at Ubinas, Peru, was spotted by pilots rising to ~6.7-9.1 km / 20-30,000 feet.
- Explosions were heard from Suwanose-jima in Japan, but no associated ash plumes were spotted.
- It sounds like a lava dome has been spotted at Sarychev Peak in the Kuril Islands of Russia. An "intense thermal anomaly" was noted at the summit in satellite images and gas/steam plumes have been seen each day. However, no new ash plumes have been noticed since June 16.

pretty interesting seismogram at yellowstone today:

A couple of days ago an ash cloud from Sarychev reached Finland, about 8000 km away in west. It was flying high in the stratosphere. The weather camera of Tampere amateur astronomers recorded it:

The camera points north. And yes, at this time of the year the Sun really sets almost due north. And pops up again pretty soon. Latitude is about 61.5N.
AVO responded to an emailed inquiry on the persistent strong SO2 signals observed for several weeks over the Aleutians - enough to make me wonder if there was a local source of emissions. They confirmed the source as Sarychev.
Interesting Doug. Thanks for the heads up.
Looking at the location of that web recorder, is that not the focus of the earthquake swarm from a few months back?
