Archeology - Tsunami Generated by the Late Bronze Age Eruption of Thera

—Tsunami
were generated during the Late Bronze Age (LBA) eruption of the island
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 deep-sea sedimentary deposits in the eastern Mediterranean Sea
known as homogenites; open-ocean wave heights of about 1.9–17 m are
estimated. Tsunami generated by the entry of pyroclastic flows/surges
and lahars/debris flows into the sea propagated in all directions around
the island; wave heights along coastal areas were about 7–12 m as
estimated from newly identified tsunami deposits on eastern Thera as
well as from pumice deposits found at archaeological sites on northern
and eastern Crete.
