1967 Neiva Earthquake
The 1967 Neiva earthquake occurred at 10:24 local time ( UTC-05) on February 9 in Colombia. The epicentre of the earthquake was located in San Vicente del Caguán in the department of Caquetá. The earthquake, associated with the Algeciras Fault, part of the megaregional Eastern Frontal Fault System, had a moment magnitude of 7.0 and an intensity of VIII and was felt in northwestern South America from Caracas to Iquitos and Buenaventura to Mitú. In the following months, 350 aftershocks were registered in the area. The earthquake produced 98 fatalities and approximately 600,000 USD in damage. Description While the earthquake is commonly referred to as the Neiva earthquake, the epicentre was not located in Neiva as first reported,Velandia et al., 2005, p.320 or Algeciras as later reports state,Various authors, 2014, p.9 yet in San Vicente del Caguán in northern Caquetá. The earthquake had a moment magnitude of 7.0 and an intensity of VIII. The earthquake was felt from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ShakeMap
In seismology, strong ground motion is the strong earthquake shaking that occurs close to (less than about 50 km from) a causative fault. The strength of the shaking involved in strong ground motion usually overwhelms a seismometer, forcing the use of accelerographs (or strong ground motion accelerometers) for recording. The science of strong ground motion also deals with the variations of fault rupture, both in total displacement, energy released, and rupture velocity. As seismic instruments (and accelerometers in particular) become more common, it becomes necessary to correlate expected damage with instrument-readings. The old Modified Mercalli intensity scale (MM), a relic of the pre-instrument days, remains useful in the sense that each intensity-level provides an observable difference in seismic damage. After many years of trying every possible manipulation of accelerometer-time histories, it turns out that the extremely simple peak ground velocity (PGV) provides th ...

Neiva, Huila
Neiva () is the capital of the Department of Huila. It is located in the valley of the Magdalena River in south central Colombia with a population of about 357,392 inhabitants. It is one of the most important cities in southern Colombia, mainly because of its strategic geographical location. History Neiva was first founded in 1539 by Juan de Cabrera in an area now belonging to the municipality of Campoalegre. In 1550, Juan de Alonso y Arias relocated the city to the place that is now the municipality of Villavieja. At this location, the city was destroyed by indigenous tribes in 1560. The city was founded, at its current location, for the third and final time in 1612 by Diego de Ospina y Medinilla. Neiva became important during the colonial times because of its strategic location. It was located in the trade route that communicated the Viceroyalty of Peru with Bogotá and Caracas. The city was declared as the capital of the Province of Neiva, made up of the Neiva, La Plata, Ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Centers For Environmental Information
The National Centers for Environmental Information (NCEI), an agency of the United States government, manages one of the world's largest archives of atmospheric, coastal, geophysical, and oceanic data, containing information that ranges from the surface of the sun to Earth's core, and from ancient tree ring and ice core records to near-real-time satellite images. NCEI is operated by the National Environmental Satellite, Data, and Information Service (NESDIS), an office of the National Oceanic and Atmospheric Administration (NOAA), which operates under the U.S. Department of Commerce. In addition to archiving data, NCEI develops products and services that make the data readily available for use by scientists, government officials, the business community, academia, non-governmental organizations, and the general public. History NCEI was created in 2015 from the merger of three NOAA data centers: # National Climatic Data Center (NCDC) # National Geophysical Data Center (NGDC ...

La Uribe
La Uribe is a town and municipality in the Meta Department Meta () is a department of Colombia. It is close to the geographic center of the country, to the east of the Andean mountains. A large portion of the department, which is also crossed by the Meta River, is covered by a grassland plain known as ..., Colombia. History The population of Uribe goes back to 1886 elevated to municipality in 1921 that included the metropolitan area of San Juan de Arama according to the Decree No. 940 of 1921. In 1925, Uribe ceased to be a municipality, passing again to corregimiento intendencias. However, within the urban area of Uribe as the oldest. Its name corresponds to the surname of Antonio Uribe, one of the two partners of the latifundist Company Colombia, that with the official permission exploded the immense natural forests of quinine of the region. Its historical antecedents go back approximately to the year 1865 when the quinera company Compañía Colombia, of the company Herr ...

South American Plate
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. The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the oceanic crust of the North American Plate. At the Chile Triple Junction, near the west coast of the Taitao– Tres Montes Peninsula, an oceanic ridge known as the Chile Rise is actively subducting under the South American Plate. Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: "Parts of the plate boundaries consisting of alternations of ...

North Andes Plate
The North Andes Plate or North Andes Block is a small tectonic plate ( microplate) located in the northern Andes. It is squeezed between the faster moving South American Plate and the Nazca Plate to the southwest. Due to the subduction of the Malpelo and Coiba Plates, this area is very prone to volcanic and seismic activity, with many historic earthquakes. Boundaries The North Andes Plate is bound by (clockwise from north): # Caribbean Plate # South American Plate # Malpelo Plate (before 2017 considered part of Nazca Plate)Zhang et al., 2017 # Coiba Plate (before 2016 considered part of Nazca Plate)Chiarabba et al., 2016, p.22 # Panama Plate Terranes The Colombian part of the North Andes Plate is subdivided into several terranes:Gómez Tapias et al., 2015, p.209 Tectonics Subduction of the Coiba Plate underneath the North Andes Plate causes frequent earthquakes in the Bucaramanga Nest, the most seismically active area in the world.

Strike-slip Fault
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 ...

Brazil
Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo.
