First photographs and more detailed information about the large eruption of Sierra Negre are emerging. As on Monday, 24 October, lava flows from a fissure have travelled 9-10 km away from the fissure. The eruption is accompanied by strong lava fountains. Near the eruption site, the terrain consists mainly of older, unvegetated lava flows. Two flows are travelling towards Elizabeth Bay, while a third one is heading towards Cartago Bay, both uninhabited areas.
The popoluation of Puerto Villamil is not threatened because of its sheltered position at the S of the island.


---
Backgound: Sierra Negre is the largest of the Galapagos volcanoes, with a caldera 10 km in diameter. Its last eruptino occurred in 1979; the lava flows of that eruption did not pose any significant risk to the population of the island.

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
