Your weekly dose of volcano news brought you by the Smithsonian Institute GVP and the USGS.
This week's highlights (not counting Sarychev Peak and Turrialba) include:
- 13,000 foot / 4 km ash plumes from Rinjani in Indonesia. This is part of the continuing eruption there.
- The alert level was lowered at Galeras, Colombia to "Orange" after intense eruptions last week.
- The current lava dome at Redoubt is 1 km long, 460 m wide, and 200 m high according to the latest images from the Alaskan volcano.
- 18,000-23,000 foot / 4.8-7.7 km ash plumes from Shiveluch in Kamchatka, along with thermal anomalies over the lava dome, suggesting new magma at the surface.
- More ash emitted from Ubinas in Peru, reaching 26,000 feet / 7.9 km.

I came across some photos submitted by an unidentified person who posted photos of ash and debris floating in the Caribbean ( looked like pomice stone) and a plume of mud rising from a newly formed island in the Swan Island area after the Honduras area earthquake on May 28, 2009. This is what the author of e-mail claims. What is officially know about this?

Marcos: If you could locate a link for these photos it would be interesting. Open to correction, but I would have thought that a volcanic connection was VERY unlikely off the Caribbean coast of Central America, the volcanic chain is down the western (Pacific) coast
Interested to hear if true about Swan Island
