Killer Tsunamis From Ancient Eruption Reshaped Eastern Mediterranean Life, Culture

The massive eruption of the Thera volcano in the Aegean Sea more than 3,000 years ago produced killer waves that raced across hundreds of miles of the Eastern Mediterranean to inundate the area that is now Israel and probably other coastal sites, a team of scientists has found.

The team, writing int he October issue of Geology, said the new evidence suggested that giant tsunamis from the catastrophic eruption hit “coastal sites across the Eastern Mediterranean littoral.” Tsunamis are giant waves that can crash into shore, rearrange the seabed, inundate vast areas of land and carry terrestrial material out to sea.

The region at the time was home to rising civilizations in Crete, Cyprus, Egypt, Phoenicia and Turkey.

For decades, scholars have suggested that the giant eruption, just 70 miles from Crete, might have brought about the mysterious collapse of Minoan civilization at the peak of its glory. The remnants of Thera’s eruption today make up a circular archipelago of volcanic Greek isles known as Santorini.

Thera is thought to have erupted between 1630 and 1550 B.C., or the Late Bronze Age, a time when many human cultures made tools and weapons of bronze. Scholars say the tsunamis and dense clouds of volcanic ash from the eruption had cultural repercussions that rippled across the Eastern Mediterranean for decades, even centuries. The fall of Minoan civilization is usually dated to around 1450 B.C. Geologists judge the eruption as far more violent than the 1883 eruption of the volcanic island of Krakatoa in Indonesia, which killed more than 36,000.
