Etna tsunami

from Wikipedia, the free encyclopedia

The Etna tsunami was the result of a massive debris avalanche approx. 8300 years ago ( approx. 6300 BC ) on the Etna volcano in Sicily . The Valle del Bove on Etna is the still visible sign of the landslide. The rock masses that slipped into the sea had a volume of about 35  km³ ; they caused a tsunami that hit mainly the central Mediterranean area , in particular southern Italy , western Greece and North Africa ( Libya , Tunisia ). The theory is controversial.

The deposition of so-called homogenites , which are found off Calabria , in the Great Syrte , on the deep-sea plains of the Mediterranean and in the Ionian Sea , is attributed to the tsunami . Homogenite is a term for special deposits that appear transparent in seismic profiles and were found in deep boreholes as homogeneous gray marl without internal structure. The superimposition of several such deposits, which can be detected primarily in the Great Syrte, suggest that such events, such as the Etna tsunami, were repeated several times and also occurred more recently. Currently, the eastern flank of today's volcano has a tendency to slide east into the sea and is monitored for this.

The Neolithic city ​​of Atlit-Yam on the coast of today's Israel could also have been affected by the Etna tsunami ; it was apparently abandoned at about the same time. This view, however, is not recognized especially by the archaeologists working in Atlit-Jam, since they believe that the findings point to a rather slow rise in sea levels at the time.
