Months of sometimes violent volcanic activity are striking the Greek Island of Santorini

Tremors announced an extended period of volcanic activity on and near the Greek Island of Santorini, one of the Cyclades.  Over the next month, explosions were heard, buildings were damaged, small eruptions plagued the area, sea water temperatures were raised, and most remarkably, during February a small island emerged just off the coast of the island, later to fall back into the Aegean.  (By John Osborne)
