Septentrional-Oriente Fault Zone
The Septentrional-Orient fault zone (SOFZ) is a system of active fault, active coaxial left lateral-moving fault (geology)#Strike-slip faults, 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. The SOFZ shares approximately half of the relative motion between the North American plate, North American and Caribbean plate, Caribbean tectonic plates with the Enriquillo-Plantain Garden fault zone and Walton fault zone which run along the southern side of Hispaniola and aong the southern margin of the Cayman Trough. Both fault zones terminate at the Mid-Cayman Rise to the west. Some researchers believe that the Enriquillo-Plantain Garden fault zone and the SOFZ bound a microplate, dubbed the Gonâve Microplate, a area of the northern Caribbean Plate that is in the process of shearing off the Caribbean Plate and accreting to ...

Geological Society Of America
The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Procter and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, US, since 1967. GSA began with 100 members under its first president, James Hall. In 1889 Mary Emilie Holmes became its first female member. It grew slowly but steadily to 600 members until 1931, when a nearly $4 million endowment from 1930 president R. A. F. Penrose Jr. jumpstarted GSA's growth. As of December 2017, GSA had more than 25,000 members in over 100 countries. The society has six regional sections in North America, three interdisciplinary interest groups, and eighteen specialty divisions. Activities The stated mission of GSA is "to advance geoscience research and discovery, service to society, stewardship of Earth, an ...

Geology Of The Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...

Geography Of Hispaniola
Geography (from Ancient Greek, Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and world, its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the Tobler's first law of geography, first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismic Faults Of North America
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zh ...

List Of Earthquakes In Haiti
Some of the earthquakes in Haiti have been very destructive to the country. The widespread damage and high-number of casualties of events in 2010 and 2021 can be partially blamed on the fact that most of the population in Haiti resides in structures that are vulnerable to earthquake shaking, in which they are made of stone and concrete.

Supershear Earthquake
In seismology, a supershear earthquake is an earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity. This causes an effect analogous to a sonic boom. Rupture propagation velocity During seismic events along a fault surface the displacement initiates at the focus and then propagates outwards. Typically for large earthquakes the focus lies towards one end of the slip surface and much of the propagation is unidirectional (e.g. the 2008 Sichuan and 2004 Indian Ocean earthquakes). Theoretical studies have in the past suggested that the upper bound for propagation velocity is that of Rayleigh waves, approximately 0.92 of the shear wave velocity. However, evidence of propagation at velocities between S-wave and compressional wave (P-wave) values have been reported for several earthquakesArchuleta,R.J. 1984A faulting model for the 1979 Imperial Valley earthquake J.

Cayman Islands
The Cayman Islands () is a self-governing British Overseas Territory—the largest by population in the western Caribbean Sea. The territory comprises the three islands of Grand Cayman, Cayman Brac and Little Cayman, which are located to the south of Cuba and northeast of Honduras, between Jamaica and Mexico's Yucatán Peninsula. The capital city is George Town on Grand Cayman, which is the most populous of the three islands. The Cayman Islands is considered to be part of the geographic Western Caribbean Zone as well as the Greater Antilles. The territory is a major world offshore financial centre for international businesses and wealthy individuals, largely as a result of the state not charging taxes on any income earned or stored. With a GDP per capita of $91,392, the Cayman Islands has the highest standard of living in the Caribbean. Immigrants from over 130 countries and territories reside in the Cayman Islands.

2020 Jamaica Earthquake
At 2:10 p.m. local time ( UTC-5) on 28 January 2020, an earthquake of 7.7 struck on the north side of the Cayman Trough, north of Jamaica and west of the southern tip of Cuba, with the epicenter being 80 miles (130 km) ESE of Cayman Brac, Cayman Islands or 83 miles (134 km) north of Montego Bay, Jamaica. Schools in Jamaica and buildings in Miami were evacuated after shaking was observed in parts of the U.S. state of Florida. Light shaking was also reported on the Yucatan peninsula in Mexico. It is the largest earthquake in the Caribbean since 1946. A tsunami warning for the Caribbean Sea was issued by the Pacific Tsunami Warning Center and later withdrawn. Tectonic setting The eastern part of the Cayman Trough forms part of the Gonâve Microplate, which lies between the North American Plate and the Caribbean Plate. It is bounded to both north and south by large transform faults that together accommodate the relative displacement of the two major plates. To the n ...

Cap-Haïtien
Cap-Haïtien (; ht, Kap Ayisyen; "Haitian Cape"), typically spelled Cape Haitien in English and often locally referred to as or , is a commune of about 190,000 people on the north coast of Haiti and capital of the department of Nord. Previously named ''Cap‑Français'' ( ht, Kap-Fransè; initially ''Cap-François'' ht, Kap-Franswa) and ''Cap‑Henri'' ( ht, Kap-Enri) during the rule of Henri I, it was historically nicknamed the ''Paris of the Antilles'', because of its wealth and sophistication, expressed through its architecture and artistic life. It was an important city during the colonial period, serving as the capital of the French Colony of Saint-Domingue from the city's formal foundation in 1711 until 1770 when the capital was moved to Port-au-Prince. After the Haitian Revolution, it became the capital of the Kingdom of Haiti under King Henri I until 1820. Cap-Haïtien's long history of independent thought was formed in part by its relative distance from Port-au-Pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1842 Cap-Haïtien Earthquake
The 1842 Cap-Haïtien earthquake occurred at 17:00 local time (21:00 UTC) on 7 May. It had an estimated magnitude of 8.1 on the scale and triggered a destructive tsunami. It badly affected the northern coast of Haiti and part of what is now the Dominican Republic. Port-de-Paix suffered the greatest damage from both earthquake and tsunami. Approximately 5,000 people were killed by the effects of the earthquake shaking and another 300 by the tsunami. Tectonic setting The island of Hispaniola lies across the complex transform plate boundary between the North American Plate and the Caribbean Plate. The overall four cm per year displacement along this boundary is split nearly equally between two major dextral (right lateral) strike-slip zones either side of the Gonâve Microplate. To the south is the Enriquillo–Plantain Garden fault zone, which extends from Jamaica in the west to the south-east of Hispaniola to the east. In the north the fault zone is the Septentrional-Oriente fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
