November 30, 1823 Tsunami: Saint Pierre, Martinique

At 2:45 local time a strong earthquake was followed by a tsunami at 3:10 am. Mallet (Reference #497) said, "The sea rose after the shock, and occasioned some damage in the harbours." There was damage in Saint-Pierre Harbor.

Reference #9688:

Archived exactly one year apart, respectively on 30 November 1823 and 30 November 1824, both of these events purportedly caused ‘damages in the harbour’ on those two dates - seemingly the Saint-Pierre harbour. Moreover, both events appear to have occurred following periods of high temperatures that were accompanied by torrential rains (Mallet, 1852, 1853, 1854). These similarities lead to two distinct hypotheses. It is entirely possible that these two purported tsunamis were in fact one single event, wrongly reported as separate events due to transcription of calendar mistakes. Alternatively, it is somewhat possible that the two events resulted from earthquakes that occurred exactly one-year apart. However it is highly unlikely that such coincidence in the day and month actually occurred. Finally, it is also entirely possible that the reported tsunamis were storm surges generated by hurricanes.
