December 26, 1861 Tsunami: Corinth Gulf, Greece

The "earthquake took place on both the shores of the Gulf of Corinth within its western half. The area where the earthquake was felt stretched in the latitudinal direction and embraced the gulf. The coastal plain on the southern shore of the gulf was separated from the foot of the northern slope of the Peloponnesus mountain massif. A fissure 2m wide and 13km long formed from Pounda to Gardhena. The entire loose cover of the plain moved northward and partially slipped into the water of the gulf. Numerous sand craters were formed of diameters from centimeters up to 20 m." Many houses and buildings were destroyed or damaged. (reference #2130)
