1766 Southeastern Caribbean Earthquake
Venezuela and Trinidad were struck by a major earthquake on 21 October 1766 at 4:30 in the morning local time in Cumaná, Venezuela (4:45 local time in Trinidad). It caused widespread damage from Caracas in the west to Georgetown, Guyana in the east. Despite the significant damage caused, there are no reports of casualties associated with this earthquake. It had an estimated magnitude in the range 6.5–7.5 and a maximum felt intensity of IX-X (''destructive'' to ''very destructive'') on the European macroseismic scale. It was felt from Guadeloupe in the north to the Ventuari River in the south and Maracaibo in the west and Kaw, French Guiana in the east. Tectonic setting The southeastern margin of the Caribbean lies above the complex boundary between the Caribbean Plate and the South American Plate. In northern Colombia and western Venezuela, the Caribbean Plate is subducting obliquely beneath the North Andes Plate (part of the South American Plate). East of Trinidad, the South ...

Cumaná
Cumaná () is the capital city of Venezuela's Sucre State. It is located east of Caracas. Cumaná was one of the first cities founded by Spain in the mainland Americas and is the oldest continuously-inhabited Hispanic-established city in South America. Its early history includes several successful counters by the indigenous people of the area who were attempting to prevent Spanish incursion into their land, resulting in the city being refounded several times. The municipality of Sucre, which includes the capital city, Cumaná, had a population of 358,919 at the 2011 Census; the latest estimate (as at mid 2016) is 423,546.Instituto Nacional de Estadistica, Caracas. The city is located at the mouth of the Manzanares River on the Caribbean coast, in the northeast of Venezuela. It is home to first and most important of the five campuses of the Universidad de Oriente, and is a busy maritime port, home of one of the largest tuna fleets in Venezuela. The city is close to Mochima Nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Historical Earthquakes
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the beginning of the 20th century. As the events listed here occurred before routine instrumental recordings, they rely mainly on the analysis of written sources. There is often significant uncertainty in location and magnitude and sometimes date for each earthquake. The number of fatalities is also often highly uncertain, particularly for the older events. Pre-11th century 11th–18th centuries 19th century Source for all events with 'USGS' labelled as the source United States Geological Survey (USGS''Note: Magnitudes are generally estimations from intensity data.

Aimé Bonpland
Aimé Jacques Alexandre Bonpland (; 22 August 1773 – 11 May 1858) was a French explorer and botanist who traveled with Alexander von Humboldt in Latin America from 1799 to 1804. He co-authored volumes of the scientific results of their expedition. Biography Bonpland was born as Aimé Jacques Alexandre Goujaud in La Rochelle, France, on 22, 28,. or 29 August 1773. His father was a physician and, around 1790, he joined his brother Michael in Paris, where they both studied medicine. From 1791, they attended courses given at Paris's Botanical Museum of Natural History. Their teachers included Jean-Baptiste Lamarck, Antoine Laurent de Jussieu, and René Louiche Desfontaines; Aimé further studied under Jean-Nicolas Corvisart and may have attended classes given by Pierre-Joseph Desault at the Hôtel-Dieu. During this period, Aimé also befriended his fellow student, Xavier Bichat. Amid the turmoil of the French Revolution and Revolutionary Wars, Bonpland served as ...

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected t ...

Hypocenter
In seismology, a hypocenter or hypocentre () is the point of origin of an earthquake or a subsurface nuclear explosion. A synonym is the focus of an earthquake. Earthquakes An earthquake's hypocenter is the position where the strain energy stored in the rock is first released, marking the point where the fault begins to rupture.''The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus.'' This occurs directly beneath the epicenter, at a distance known as the ''hypocentral depth'' or ''focal depth''. The focal depth can be calculated from measurements based on seismic wave phenomena. As with all wave phenomena in physics, there is uncertainty in such measurements that grows with the wavelength so the focal depth of the source of these long-wavelength (low frequency) waves is difficult to determine exactly. Very strong earthquakes radiate a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoseismal Map
In seismology, an isoseismal map is used to show lines of equally felt seismic intensity, generally measured on the Modified Mercalli scale. Such maps help to identify earthquake epicenters, particularly where no instrumental records exist, such as for historical earthquakes. They also contain important information on ground conditions at particular locations, the underlying geology, radiation pattern of the seismic waves, and the response of different types of buildings. They form an important part of the macroseismic approach, i.e. that part of seismology dealing with noninstrumental data. The shape and size of the isoseismal regions can be used to help determine the magnitude, focal depth, and focal mechanism of an earthquake. History The first known isoseismal map was produced for the 1810 earthquake in Mór in Hungary, and published by Kitaibel and Tomtsányi in 1814. The first, six-level intensity scale was proposed by Egen in 1828 for an earthquake in Rhineland. Rober ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike-slip
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can bl ...
