Augustine volcano, Alaska: eruption update
Augustine volcano has calmed down a bit, and the USGS lowered the alert level from RED to ORANGE. Seismic activity has declined since yesterday’s eruption but remains elevated above background and the volcano continues to steam vigorously. AVO reports steam and minor ash emissions from a new vent on the 1986 lava dome, producing a plume reaching an estimated height of 8000 to 10,000 ft (2400 to 3050 m) above sea level. Field observataions confirmed mudflows (also visible in the on-island web camera) on the flanks of the volcano. These flows are the likely source of false reports of new lava flows on the volcano.

The tours this year on Santorini are now over, too, with lots of fun and great company as well. Thanks to all participants!
Before we send out our formal newsletter, when the programs for 2006 are completed, a quick notice to announce that Tom will offer a new, 12-days tour / expedition to the Rift Valley including Lengai volcano in Feb. and summer 2006, Costa Rica in late March and (probably) July 2006. As well, Tobias (who is right now touring in the Saronic Gulf) awaits with a new, exciting program on Milos, a wonderful, volcanic island in Greece! Other new or recently developped programs include Nisyros (Greece) and the Eifel region in Germany (details will come soon).
Greetings from Athens! Tom

Igneous or magmatic rocks
: The most primitive rock type forms when magma (molten rock) solidifies - either inside the earth (plutonic rocks) or during volcanic eruptions (volcanic rocks). A short overview.

Videos taken during our volcano expeditions and tours, showing eruptions, volcanic phenomena and more.
: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
