What the record says

NCEI’s account, from the sources it cites.

Reference #14362:

"…there was a violent storm on the island of Martinique, followed by a powerful earthquake that shook the island terribly. The city of Saint- Pierre, with the exception of only a few courtyards, was reduced to ruins... 80 ships sank in various harbors of the island... and a large part of the island was submerged by the sea”

The islands of St. Kitts, Nevis, and Marie-Galante, “…there was an extraordinary rise and fall of the tide off the island of St. Christopher. The same was observed off the islands of Nevis and Marie-Galante. The water suddenly rose and fell by 6 feet”

above found in the newspaper St. Petersburg Vedomosti.

Note: it is possible that the storm and earthquake impacts from the same time frame were combined
