We are lucky to have Dr. Boris Behncke of the INGV Catania as that blogger and he brings us a three-part series on Mt. Etna on the island…

Lava flows from Kilauea in Hawai`i move towards a home in Kalapana. Whenever I think about the hazards posed by most lava flows, I tend to think about the opening scene in the Hitchhiker’s Guide to the Galaxy.
