Dating the thera eruption
They interpret them as air-fall deposits of phreatic and phreatomagmatic activity from a vent near the present-day Nea Kameni island that preceded the eruption with a short time interval in the range of some months.Thus, they possibly provided a warning to the inhabitants.That fiery explosion killed upwards of 40,000 people in just a few hours, produced colossal tsunamis 40 feet tall, spewed volcanic ash across Asia, and caused a drop in global temperatures and created strangely colored sunsets for three years. Thera's eruption was four or five times more powerful than Krakatoa, geologists believe, exploding with the energy of several hundred atomic bombs in a fraction of a second.An absence of human remains and valuables like metal suggest that the Minoan residents of Santorini predicted the eruption and the island was evacuated, but the culture as a whole did not fare as well.
When the Greek philosopher Plato described the lost city of Atlantis over a thousand years after the volcanic eruption, he may have been referring to Thera folklore passed down in Greece over many generations and exaggerated like a game of broken telephone.
It mantles uniformly the pre-Minoan surface which proofs its origin as fall-out.
A clear southeasterly trend in greatest accumulations reflects the dispersal of the tephra-bearing eruption column by strong atmospheric winds (Bond and Sparks, 1976).
The first pumice fall deposit near Athinios, here about 5 m thick.
Walter Friedrich points to holes in the deposit that once were the trunk and branches of a tree.
