What the record says

NCEI’s account, from the sources it cites.

A disastrous earthquake occurred at Pointe-a-Pitre, Guadeloupe. It was felt at Antigua, St. Lucia, St. Kitts, Montserrat, Martinique, and other islands. At Antigua, the sea rose 1.2 m and sank again immediately.

Following Bernard and Lambert [1988], no significant tsunami was promoted by the 1843 earthquake, whereas Shepherd [1992] mentioned several observations of tsunami reported in Antigua and Nevis. (reference #13355)

Note: Many news articles (e.g. refs # 13201) state that Grand Cayman sunk due to an earthquake in 1843, ref #13202 attributes it to the 08 Feb 1843 Guadeloupe event. However, many newspapers (including refs #13203, #13204) quickly discredited the reports of Grand Cayman sinking
