Somehow I missed a week of the SI/USGS Weekly Volcano Activity Reports and almost missed another. Here is this week's update!
Highlights (not including Chaiten, Soufriere Hills or Cleveland) include:
- The alert level at Galeras in Colombia was raised to Red after an explosion on September 30 and returned to orange ... and then yellow ... after activity tapered.
- Sakurajima in Japan produced 1.8-4.3 km / 6,000-14,000-tall ash-and-steam plumes, along with incandescent tephra that was thrown almost two kilometers from the vent.
- Multiple steam-and-ash plumes reached 4.3 km / 14,000 feet at Langila in the New Britain Islands.
- Sangay in Ecuador produced ash plumes that reached as high as 7.6 km / 25,000 feet.

Maybe I should just apologize right here and now for that title, but dang, I liked it.
Anyway, I've seen a lot of plume images cross my browser/inbox over the last day, so I thought I'd post a few of them.
Your weekly dose of volcanic activity from the USGS/SI. (a little late thanks to an exciting day of column chemistry).
Some highlights include:
Quick hit post from beautiful Walnut, Iowa, but this was too interesting to pass up...

All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP!
