What the record says

NCEI’s account, from the sources it cites.

1914, November 27, 14:40 UTC. 38.75 N, 20.5 E, earthquake intensity X, magnitude 6.25, tsunami intensity 4. In the Ionian Sea on the island of Levkas, a strong earthquake caused considerable destruction in the western part of the island. 14 people were killed, many houses collapsed. Individual buildings crumbled down in the town of Levkas, and especially in its coastal part, on the artificially created ground, and the rest were seriously damaged. Tile and plaster crumbled from aseismic and frame buildings, 2 inhabitants were killed in such buildings. The lighthouse in the south - western part of the island and the Castle of Ay. Nikolaos situated nearby remained unharmed.

The water level in wells was changed. Numerous collapses, though not large, occurred in mountains especially on the western slopes of the hill Pephkoulia. Collapses of soil took place near the settlements of Athanio and Komilio (a shepherd was buried near Komilio).

Numerous stone screes 1 - 3 m2 in volume took place, especially along Ay. Petros-Komilio-Khortata road; some of them caused damage to buildings in Khortata and in Colvata, especially in the vicinity of Poros. Numerous fissures 0.3 m wide and 0.5 - 1.0 m deep were formed on the road of Levkas - Ay. Nikitas along a segment 3 km long. Insignificant violations of underground water conditions were noted. An earthquake magnitude of IV was felt on the Island of Kerkyra, III - in Kiparissia, III - in Aiyion, II in Larisa, III- in Ioannina. The diameter of the zone where the earthquake was felt was 165 km. About 50 successive shocks occurred during the following day and night, including 2 considerably strong ones. 17 more shocks of magnitude 3 - 4 were recorded up to the end of December.

The large landslide that occurred during the earthquake from the northern artificial coast of the estuary of the River Demossari resulted in fissures of 8 - 10 m and in subsidence of the breakwater in Nydri located nearby. A wave 2 - 3 m high (from other data, 11 m) was generated as a result of this landslide.
