Can an earthquake from outside of the Caribbean region cause a tsunami?
Yes, a tsunami may be generated from earthquakes occurring both within and outside of the region. In 1766 the Great Lisbon earthquake near Portugal caused a tsunami “as high as the upper storeys of houses” on the east coast of Martinique. Waves 2m high were also observed at the east coast of Barbados. Click here for more information on historical tsunamis in the Caribbean.
