Remolino-El Charco Fault
The Remolino-El Charco Fault ( es, Falla de Remolino-El Charco) is a dextral strike-slip fault in the department of Nariño in Colombia. The fault has a total length of and runs along an average northeast to southwest strike of 046.4 ± 6 in the Tumaco Basin along the Pacific Coast of Colombia. Etymology The fault is named after Remolino Grande and El Charco, Nariño.Paris et al., 2000a, p.55 Description The Remolino-El Charco Fault extends through the Pacific coastal lowlands and plains of Colombia to the east of the city of Tumaco. The fault begins in the southwesternmost point of Colombia and runs towards Guapi.Paris et al., 2000b It is close to and parallels the coast. It displaces alluvial fan sediments of the Patía, Mira, and Telembí Rivers and some Pleistocene marine terraces. The fault appears to be a southern continuation of the Naya-Micay Fault. The fault has a very well defined fault line on aerial photographs and satellite images. Pattern of deflection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alluvial Fan
An alluvial fan is an accumulation of sediments that fans outwards from a concentrated source of sediments, such as a narrow canyon emerging from an escarpment. They are characteristic of mountainous terrain in arid to semiarid climates, but are also found in more humid environments subject to intense rainfall and in areas of modern glaciation. They range in area from less than to almost . Alluvial fans typically form where flow emerges from a confined channel and is free to spread out and infiltrate the surface. This reduces the carrying capacity of the flow and results in deposition of sediments. The flow can take the form of infrequent debris flows or one or more ephemeral or perennial streams. Alluvial fans are common in the geologic record, such as in the Triassic basins of eastern North America and the New Red Sandstone of south Devon. Such fan deposits likely contain the largest accumulations of gravel in the geologic record. Alluvial fans have also been found on Mars ...

Strike-slip Faults
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 blur the ...

Seismic Faults Of Colombia
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 ...

Malpelo Plate
The Malpelo Plate is a small tectonic plate (microplate) located off the coasts west of Ecuador and Colombia. It is the 57th plate to be identified. It is named after Malpelo Island, the only emerged part of the plate. It is bounded on the west by the Cocos Plate, on the south by the Nazca Plate, on the east by the North Andes Plate, and on the north by the Coiba Plate, separated by the Coiba Transform Fault (CTF). This microplate was previously assumed to be part of the Nazca Plate. The Malpelo Plate borders three major faults of Pacific Colombia, the north to south striking Bahía Solano Fault in the north and the Naya-Micay and Remolino-El Charco Faults in the south. Description The Malpelo Plate was identified by a non-closure of the Nazca-Cocos-Pacific plate motion circuit, reported by Tuo Zhang and lead-researcher Richard G. Gordon et al. of Rice University in a paper published in August 2017.Zhang et al., 2017 The existence of the plate has been hypothesised be ...

List Of Earthquakes In Colombia
This is a list of earthquakes in Colombia. Colombia is a seismically active country and has a large seismic risk in many areas of its territory due to its location at the boundaries of the Malpelo, Panama, Caribbean, North Andes (where most earthquakes occurred) and South American Plates along the Pacific Ring of Fire. The southeastern and extreme eastern portions of Colombia are not as seismically active as the rest of the country. The first historically registered earthquake felt in Colombia occurred on September 11, 1530, around 10:00 AM, probably with the epicentre near Cumaná, Venezuela. The earthquake was documented by Gonzalo Fernández de Oviedo y Valdés in his work ''La Historia general de las Indias'' and by friar Bartolomé de las Casas in his book ''Historia de Las Indias''.Ramírez, 1975, p.63 The first documented earthquake with its epicentre in present-day Colombia territory took place in 1566,Ramírez, 1975, p.65 with the epicentre estimated around Santander ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...
