Stromboli volcano: eruption update
Eruption from the central vent of Stromboli (30 Dec. 2005, photo: Karen B.)
Stromboli continues to be very active. Loud eruption noises are frequently audible all over the island. On a visit by VolcanoDiscovery team members Karen and Tom on the afternoon of 30 Dec. 2005 the following activity was observed:
One active vent in the West crater produced tall, candle-like strombolian eruptions in intervals of 10-15 minutes, throwing incandescent material up to 200-250 m above the crater. 3 vents were active in the central crater, all of them glowing constantly, and relatively strongly spattering; small boiling lava lakes present few meters below the crater rim can be inferred. The northermost of these vents, forming a tall cone, also had strong strombolian eruptions at irregular intervals of 5-25 minutes, throwing lots of very hot, incandescent bombs to up to 100-150m elevation, frequently outside the crater complex. At least one vent was active in the NE crater, which unfortunately was today completely hidden by fumes. It did not erupt visible bombs, but every 10-20 minutes it produced loud hissing noises; we assume that it erupted mainly gas.
The level of activity is surprisingly high, comparable to what it had been in late 2002, just before the effusive eruption that lasted into June 2003. It appears the activity has more or less been so since at least October 2005; in other words, the magma column inside the conduits must be very high. We think that a new effusive eruption (a lava flow emerging from the craters) might not be too far away. Who knows?

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 ... alles lesen
