SI/USGS Weekly Volcano Activity Report for 7/1-7/2009
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.
