Mediterranean Tsunamis

What apropos timing, as I was about to write up this article on the possibility of a Mediterranean tsunami, I noticed that Zoltán Sylvester over at Hindered Settling wrote an interesting article on megatsunami-chevrons.

He questions some of the methods in determining what is or isn’t a megatsunami-chevron, meaning parabolic shaped wedges of sand that may be indicative of large amounts of ocean water moving inland and dropping sediment. He notes that the geomorphilogical and sedimentalogical evidence for these chevrons is fairly weak, especially since many seem to appear as the classical parabolic eolian sand dune. It’s definitely a fascinating read.

Fresh on the heals of that post, comes this article, published on Phyorg today about the possibility and dangers posed by a tsunami in the Mediterranean. A large tsunami in 365 AD was thought to have claimed many lives around the rim of the Mediterranean sea and thought to have originated from an earthquake occuring in a subduction zone near Greece.

“The sea was driven back, and its waters flowed away to such an extent that the deep sea bed was laid bare and many kinds of sea creatures could be seen,” wrote Roman historian Ammianus Marcellus, awed at a tsunami that struck the then-thriving port of Alexandria in 365 AD.

“Huge masses of water flowed back when least expected, and now overwhelmed and killed many thousands of people… Some great ships were hurled by the fury of the waves onto the rooftops, and others were thrown up to two miles (three kilometres) from the shore.”

Ancient documents show the great waves of July 21, 365 AD claimed lives from Greece, Sicily and Alexandria in Egypt to modern-day Dubrovnik in the Adriatic.

New evidence by researchers at the University of Cambridge show that the earthquake did not happen on the subduction zone itself, but on a previously unknown fault near the subduction zone. This new information highlights the serious risk that cities and and countries along the Mediterranean face from unknown faults.

UNESCO is currently working on setting up a tsunami alert system in the Mediterranean Sea.
