What the record says
NCEI’s account, from the sources it cites.
Sept. 20, 1867. 36.4 N, 22.2 E, intensity X. Ionian Sea, Peloponnesus Peninsula and Ionian Islands. The September 20 earthquake generated tidal waves, which rolled onto the southern and western shores of the Peloponnesus Peninsula, were observed on the Ionian Islands, within the region of Shkoder in Albania, in southeastern Italy, in Brindisi where the sea receded from the shore comparatively far, on the Island of Sicily, in Messina and Catania where low water was observed at 07h09m, on the Islands of Malta, Crete, Serifos, Syros, Cyclades. Oscillations of the sea level within the focal zone of the waves lasted a long time: from 5.5 up to 10 hours before the sea finally became calm after rolling in and surging back many times. The waves became stronger in such funnelshaped gulfs and bays opened towards their supposed source as Laconia and Messini on the Peloponnesus Peninsula, Lixouri on the Island of Kefallonia, on the Island of Syros. Githio was destroyed by waves; a lot of fish were thrown out onto the coast. (reference #2130)
Sept. 20, 1867. Disastrous shock located in the Peninsula of Maina (Laconia) causing severe damage particularly at Maroulia, Areopolis and the Monastery of Gola. A large tsunami in Paganea (Kalyvia), Gythion and Skoutari, in the western Gulf Laconikos, reaching Crete, Syra, Corfu. The disturbance of the sea continued in Chania, Zakyntos and Argostoli for 4 1/2 hours. Gythion destroyed by tsunami. (reference #4139)
