What the record says

NCEI’s account, from the sources it cites.

Most probably a strong seiche (reference #29)

Earthquake in the sea about 80 km far from the southern coast of Crete. Antonopoulos (reference #29), who quotes the Bulletin of the Seismological Institute of Athens, reports that small crafts were at risk due to tsunami waves. However he postulates that the cause of the disturbance is possibly a strong seiche.

very improbable tsunami (reference #4139)
