Teletsunami from Libson, Portugal, earthquake 1755 November 1

Waves of amplitude 7 m were observed at Saba, 3.6 m at Antigua and Dominica, 4.5 at St. Martin, leaving a sloop anchored in 4.6m of water laying broadside on the dry bottom, 1.5-1.8 m at Barbados, where the wave had a period of 5 minutes and the water was black as ink. This could be a local landslide tsunami or seiche triggered by the Libson wave. At Martinique at some places the water was reported to have withdrawn for 1.6km and at other placed it flowed into the upper level rooms of the houses. The lowlands on most of the other French Islands were inundated. There is a report of Santiago De Cuba being nearly inundated in 1755 but the month and day were not given. This is probably from the Libson tsunami.
