Eastern Frontal Fault System
The Eastern Frontal Fault System ( es, Sistema de Fallas de la Falla Frontal de la Cordillera Oriental) is a megaregional system of oblique and thrust faults cross-cutting Colombia from Ecuador in the south to Venezuela in the north. The system from south to north covers ten out of 32 departments of Colombia; Nariño, Putumayo, Cauca, Huila, Caquetá, Cundinamarca, Meta, Boyacá, Casanare and Arauca. The Eastern Frontal Fault System underlies and affects the capitals of Putumayo, Mocoa, Caquetá, Florencia, Meta, Villavicencio and Casanare, Yopal. The fault system has a total length of with a cumulative length of the faults of and runs along an average northeast to southwest strike of 042.1 ± 19 bordering and crossing the Eastern Ranges of the Colombian Andes. The fault system forms the boundary between the North Andes microplate and the South American Plate. Several segments of the fault system are active, with major earthquakes occurring in historical time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordillera Oriental (Colombia)
The Cordillera Oriental ( en, Eastern Ranges) is the widest of the three branches of the Colombian Andes. The range extends from south to north dividing from the Colombian Massif in Huila Department to Norte de Santander Department where it splits into the Serranía del Perijá and the Cordillera de Mérida in Venezuelan Andes. The highest peak is Ritacuba Blanco at in the Sierra Nevada del Cocuy. Geography The western part of the Cordillera Oriental belongs to the Magdalena River basin, while the eastern part includes the river basins of the Amazon River, Orinoco River, and Catatumbo River. Within it, the Altiplano Cundiboyacense and the Sierra Nevada del Cocuy (with the only snowy peaks in this mountain range) stand out. The mountain range contains the most páramos in the world.

Mesozoic
The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is the second-to-last era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods. It is characterized by the dominance of archosaurian reptiles, like the dinosaurs; an abundance of conifers and ferns; a hot greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of significant tectonic, climatic, and evolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Active Fault
An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. * Active faulting is considered to be a geologic hazard - one related to earthquakes as a cause. Effects of movement on an active fault include strong ground motion, surface faulting, tectonic deformation, landslides and rockfalls, liquefaction, tsunamis, and seiches. Quaternary faults are those active faults that have been recognized at the surface and which have evidence of movement during the Quaternary Period. Related geological disciplines for ''active-fault'' studies include geomorphology, seismology, reflection seismology, plate tectonics, geodetics and remote sensing, risk analysis, and others. Location Active faults tend to occur in the vicinity of tectonic plate boundaries, and active fault research ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
