Thucydides on the Seismic Causes of Tsunami

Thucydides, History of the Peloponnesian War, 3. 89, ed. Thomas Hobbes.
"The next summer the Peloponnesians and their confederates came as far as the isthmus under the conduct of Agis the son of Archidamus, intending to have invaded Attica; but by reason of the many earthquakes that then happened, they turned back, and the invasion proceeded not. About the same time (Euboea being then troubled with earthquakes), the sea came in at Orobiae on the part which then was land and, being impetuous withal, overflowed most part of the city, whereof part it covered and part it washed down and made lower in the return so that it is now sea which before was land. And the people, as many as could not prevent it by running up into the higher ground, perished. Another inundation like unto this happened in the isle of Atalanta, on the coast of Locris of the Opuntians, and carried away part of the Athenians' fort there; and of two galleys that lay on dry land, it brake one in pieces. Also there happened at Peparethus a certain rising of the water, but it brake not in; and a part of the wall, the town-house, and some few houses besides were overthrown by the earthquakes. The cause of such inundation, for my part, I take to be this: that the earthquake, where it was very great, did there send off the sea; and the sea returning on a sudden, caused the water to come on with greater violence. And it seemeth unto me that without an earthquake such an accident could never happen".
