Tsunami generated by the Late Bronze Age eruption of Thera (Santorini), Greece

Tsunami were generated during the Late Bronze Age (LBA) eruption of the isl and of Thera, in the southern Aegean Sea, by both caldera collapse, and by the entry of pyroclastic surges/flows and lahars/debris flows into the sea. Tsunami generated by caldera collapse propagated to the west producing dee p-sea sedimentary deposits in the eastern Mediterranean Sea known as homoge nites; open-ocean wave heights of about 1.9-17 m are estimated. Tsunami gen erated by the entry of pyroclastic flows/surges and lahars/debris flows int o the sea propagated in all directions around the island; wave heights alon g coastal areas were about 7-12 m as estimated from newly identified tsunam i deposits on eastern Thera as well as from pumice deposits found at archae ological sites on northern and eastern Crete.
