On September 22, 2003 a M 6.5 earthquake occurred in northern Dominican Republic. This earthquake was first located by the USGS at Lat. 19.7 N and Long. 69.7 W at a depth of 10 km. This location was 15 km south of Puerto Plata, a major city dedicated to tourism and 20 km north of Santiago, the second largest city in the Dominican Republic. Between 1943 and 1953, 5 earthquakes of magnitude 7.1 to 8.1 occurred to the west of the epicenter and have been associated with the south dipping interface of the North American plate under the Caribbean (Dolan and Wald, 1998). Previous to that, other significant earthquakes occurred in the region: 1564 (the city of Santiago was destroyed), 1783, 1842, 1887, 1897 (Mann et al, 1998). These earthquakes have been associated with the Septentrional Fault system. Recent paleoseismological studies by Paul Mann and others (1998) revealed the high seismic hazard associated with the Septentrional Fault.
