Early in the Late Bronze Age, the volcano at the center of the island of Santorini (or Thera) erupted on a scale which may have had no parallel among eruptions over the past four or five millennia by volcanoes located in or near densely populated areas of the globe. The caldera (or crater) created by this eruption of the Theran volcano is said to have measured as much as 83 square kilometers in area. It presently extends down as much as 480 meters below sea level inside of the wall of cliffs which ring it and which themselves rise up as much as 300 meters above sea level.
Yup. Thera/Santorini/Akatori...was a biggie. The plume would have had to be 30 miles high to be seen in the Nile Valley of Egypt. ("Staff by day, Torch by night")
BTW, in the 1300's Thera was owned by a Jewish guy named Joseph Nazi.
