Into the Paleogene at the start of the Cenozoic, volcanism, metamorphism and plutonism continued underwater until the Eocene, still largely below water.However, by the middle Eocene, the amalgamated island arcs collided with the southern margin of the North American Plate at the Florida-Bahama Platform, leading to the formation of extensive carbonates and the end of volcanism and plutonism.
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.
This is a list of tectonic plates on Earth's surface. Tectonic plates are pieces of Earth's crust and uppermost mantle , together referred to as the lithosphere . The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium ) and continental crust ( sial ...
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 rupture process of the earthquake indicate the highly oblique motion between the two tectonic plates. [21] The restraining bend where the rupture jumped from a reverse fault to a strike-slip fault was located beneath Pic Macaya. The reverse fault, located east of the bend experienced an estimated maximum slip of 2.7 m (8.9 ft).
The 2010 Haiti earthquake was a catastrophic magnitude 7.0 M w earthquake that struck Haiti at 16:53 local time (21:53 UTC) on Tuesday, 12 January 2010. [ 8 ] [ 9 ] The epicenter was near the town of Léogâne , Ouest department , approximately 25 kilometres (16 mi) west of Port-au-Prince , Haiti's capital.
A temporary Canadian seismic sensor network of three stations has been established in Haiti along the fault, as of February 19, 2010. The network is not considered permanent, but will remain for quite some time. The stations are in secure locations, being expensive equipment, and are satellite linked to Natural Resources Canada in Ottawa. They ...
The South American plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African plate, with which it forms the southern part of the Mid-Atlantic Ridge.
