NCEI’s account, from the sources it cites.

"Grases [1971], citing Henderson's "Jamaica Almanac for 1852" [1852], reported that a series of waves and disastrous earthquakes nearly ruined the island of Jamaica. No other reports of earthquakes could be found for this day, but a major hurricane is reported. Not reported in Hall [1907]." (Lander et. al, 2002)
