What the record says

NCEI’s account, from the sources it cites.

1630, July 22. Disastrous earthquake in the islands of Ste-Maure, Levkas, Ithaki, and Kephallinia: collapse of many houses and many victims, intensity X. (reference #1093)

1630, July 2, 38.8 N, 20.8 E, magnitude 6.7, Leukada, >20 deaths. (reference #4408)

1630, July 4. Lefkas. During the second hour of the day, on 22 June 1630 (Julian calendar) there was a destructive earthquake in the Ionian Islands. In Lefkas many houses in the town and in the castle of Santa Maura, as well as a part of the aqueduct, again collapsed. At Katuna of Karioti all the houses were destroyed and trees were uprooted. Damage extended throughout the island and in some villages not a single dwelling was left standing and people were killed. Damage was reported from Kefalonia and Ithaki and the shock was strong at Zante, but there is no evidence that it caused any damage on mainland Greece. Aftershocks continued until late in September, and were also felt in Zante. (reference #9116)

Earthquake on 22 June/2 July 1630. A great earthquake happened at 8:00 a.m. modern time. In the town and in the fortress of Ayia Mavra, many houses and arches fell. In other parts of the island, houses also fell, but in some villages, all the houses fell, and their foundations were turned upside down. In addition, trees were uprooted, while in many places, the ground fissured. Many people were killed on the island. A modern author incorrectly dated the earthquake as 4 July 1630 (N.S.).
