Santorini - The island, once round, is the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption, which occurred some 3600 years ago at the height of the Minoan civilization. The eruption left a large caldera and may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 68 miles to the south, through a gigantic tsunami. Another popular theory holds that the eruption is the source of the legend of Atlantis.
