The 1907 Kingston earthquake damaged every building in Kingston, Jamaica. [1] The 2010 magnitude 7.0 earthquake occurred near Port-au-Prince along blind thrust faults associated with this fault zone. [5] [6] The 2021 Haiti earthquake (magnitude 7.2) struck Haiti's Tiburon Peninsula.
These fault zones now form part of the southern boundary of the Gonâve Microplate. The major right-stepping offset between the fault zones formed a restraining bend and led to transpression and uplift that is still active today and is the reason that the island of Jamaica is now well above sea level.

Within the trough is a slowly spreading north–south ridge which may be the result of an offset or gap of approximately 420 kilometres (260 mi) along the main fault trace. The Cayman spreading ridge shows a long-term opening rate of 11–12 mm/yr. [ 4 ] The eastern section of the trough has been named the Gonâve Microplate .
Bathymetry of the northeast corner of the Caribbean plate showing the major faults and plate boundaries; view looking south-west. The main bathymetric features of this area include: the Lesser Antilles Volcanic Arc; the old inactive volcanic arc of the Greater Antilles (Virgin Islands, Puerto Rico, and Hispaniola); the Muertos Trough; and the Puerto Rico Trench formed at the plate boundary ...
The prediction is based on research done by dozens of scientists and engineers using seismic studies, historical geological data and new information to identify nearly 500 additional fault lines ...
The Gonâve microplate, showing location of the main fault zones. The Septentrional–Orient fault zone (SOFZ) is a system of active coaxial left lateral-moving strike slip faults that runs along the northern side of the island of Hispaniola where Haiti and the Dominican Republic are located and continues along the south of Cuba along the northern margin of the Cayman Trough.
In Michigan, most fault lines that were potentially visible long ago are now buried deep under sedimentary deposits, so we often don't know they exist until an earthquake happens along them.For ...
The San Joaquin and Ortigalita fault lines are part of the Great Valley thrust fault system, Philibosian said. The earthquakes this week were located slightly north of the Ortigalita fault, in an ...
