What the record says
NCEI’s account, from the sources it cites.
On 11 April 1902, 18:35UTC, a strong earthquake of moment magnitude Mw5.7 (±0.2) ruptured near the city of Chalkis, Central Greece. According to the Book of Earthquakes, the macroseismic intensity of degree V was assigned in the Rossi–Forel scale, which corresponds to intensity VI in the modified Mercalli–Sieberg scale (MMI). In the same publication, it is noted that on the beach of the nearby New Psara village, “there was an effervescence of waves looking like a storm”. This event is published here for the first time, although it is not clear if it was a local tsunami or a standing wave in the bay. (reference #13999)
