which have occurred from antiquity to the present time in Greece, large
tsunamis are very rare on the coasts of Greece. A really great tsunami
may have started in the Aegean Sea after the tremendous explosion of
Santorin volcano, which occurred 3370 ± 100 years ago (13). After the
deposit of a layer of pumice 20-30 m thick and the emptying of the
volcanic focus, the roof of the cavern thus formed collapsed. The
centrai part, consisting of an area of 83 sq km, of the former island
Stronghyb tlius became a gigantic caldera 300-400 m deep.
Tliere is no evidence indicating whether the cobapse took place
graduaby or ab at once. In the second case a huge tsunami should have
started greater by far than that generated by the explosion of Krakatoa,
on August 27, 1883. At that time depths of 200-300 m were formed by
the sinking (24) of 2/3 of the former island of an area of 33 1/2 sq km.
Thus the cavity formed by the explosion of Santorin is about 4 times
greater than that of the Krakatoa.
