component). This fault, in an E-W direction,<br />
extended for 300 km from the Enriquillo Lake in<br />
the Dominican Republic, to the western extremity<br />
of the Tiburon Peninsula, passing less than 20 km<br />
from the south of Port-au-Prince. The earthquake<br />
affected a 70 km long segment along the fault<br />
and the seismic slip was probably between one<br />
and two metres. This fault had not produced any<br />
major earthquakes over the last ten years but is<br />
likely the source of the historic quakes 61 of 1751<br />
and 1770 (Table 31).<br />
The IPGP specialists emphasize that the Enriquillo-<br />
Fault ruptured along a segment measuring less<br />
than one third of its total length, and the other<br />
segments of the fault, situated to the east and<br />
west of the rupture are also likely to break in the<br />
decades to come, producing earthquakes equal<br />
to, or slightly above, a magnitude of 7 62 .<br />
