Abstract
We present new seismic hazard maps for the Caribbean region. The data base on which the maps
are based is a revised earthquake catalogue with uniform moment magnitudes covering the entire
Latin American and Caribbean region. The method of assessment used is the Historic
Parametric which we describe in detail in companion reports. The attenuation relationships used
have been selected from a large number of existing relationships which we consider most
appropriate for this region. The results expressed as the peak ground acceleration (PGA) with
90% probability of not being exceeded within any fifty-year period. On land areas within the
Caribbean this quantity varies from less than 16% to more than 32% of gravity. The highest
values apply to the eastern half of the island of Hispaniola, most of the Leeward Islands and
Trinidad. The lowest values are found over the central Lesser Antilles and western Jamaica, but
there is nowhere within this region where the level of seismic hazard can be considered to be
negligible. More detailed maps are available on request.
