The last seismic hazard maps for Jamaica was done by Shepherd et al (1999) under a Caribbean wide project of the Pan American Institute of Geography and History (PAIGH) with CIDA funding. A catalogue of Caribbean earthquakes including historical events was prepared for this project and a seismic hazard map reflecting Peak Ground Acceleration [PGA] in any 50-year period with a 10 % probability of exceedance [PE] (i.e. for 475-yr Return Period) was prepared for Jamaica as well as other territories in the region. The new seismic hazard maps are based on an updated Jamaica earthquake catalogue which is believed to be the most comprehensive to date. Spectral ground acceleration is presented for 0.2 and 1.0 second ambient periods, respectively for site class, 'average rock', with a 2% PE in any 50-year period. This represents a 2,475-year hazard which is in keeping with the recommendations of the International Building Code (IBC).
