What the record says
NCEI’s account, from the sources it cites.
A magnitude 5.4 Ms (USGS) earthquake at 8:02 UT occurred in the West Corinthos Gulf, Greece causing damage in the Managouli-Aiyion area and created an intensity 3 tsunami at Sergoula. (reference #1315)
In Segoula a strong local sea wave was caused by coastal slide because of the earth shaking, small fishing boats moved ashore. (reference #2130)
1984 Feb 11, Sergoula, NW Corinth Gulf, Central Greece: Moderate (M=S.5) shock. A local, moderate tsunami was caused in Sergoula beach because of a c.I 00 m long coastal landslide. Small boats moved ashore. (reference #10357)
