Which islands in the Eastern Caribbean are most susceptible to earthquakes?
The answer to this question depends on what is meant by “susceptible”. Every island in the Eastern Caribbean is within 200 km of the largest events to have occurred in the past and as such experienced damage during those earthquakes. In this context all of the islands in the Eastern Caribbean are susceptible to earthquakes. If “susceptible” means feels earthquakes most often, then those areas are near Trinidad and near Martinique.
