The volcanic eruption of Santorini was the greatest in historical times.
The radiocarbon Accelerator Mass Spectrometry (AMS) dating technique and the intcal04 calibration curve suggested a two-sigma range date between 16 BC.The debate continues; the papers here cover the radiocarbon results, the ice cores, the geology, and the archaeology, offering in-depth access to a controversy linking the natural sciences and the humanities.Aside from volcanologists, it will interest scholars of Bronze Age Aegean archaeology, the chronology of the eastern Mediterranean in the second millennium BC, archaeological methodology, the principles of radiocarbon dating and its application to Bronze Age sources.The geologist Tom Pfeifer found a charred tree trunk that had stuck in the caldera wall, which had been covered by the pumice of the first phase of the Minoan eruption.This must have been an olive tree on which scientists implemented a modern method of radiometric in order to define the exact date of the eruption.
According to the results, it must have occurred in 1630-1600 BC.
Three thousand years later (1650 AD) a tidal wide flooded to the east valley of the Thera, in particular at cape Koloumbo, Perissa and Kamari beaches as well as at Akrotiri.
This wave transferred a large amount of the volcanic material that had been laid down during the eruption, from one part of the island to another.
What is more, these materials decayed as the centuries went by or even corrupted due to human activities.
This made the efforts for the defining of the eruption date even harder.
Geologists have tried to find out the age of the volcanic rocks of Santorini, some of which date back to Pliocene era by taking advantage of the properties of calcium and argon as well as the radioactive disintegration of calcium.
