Ibagué Fault
The Ibagué Fault ( es, Falla de Ibagué) is a major dextral slightly oblique strike-slip fault in the department of Tolima in central Colombia. The fault has a total length of and runs along an average east-northeast to west-southwest strike of 067.9 ± 11 cross-cutting the Central Ranges of the Colombian Andes. The fault is part of a regional shear zone and has been active in historical times, possibly associated with the 1825 Ibagué earthquake and an earthquake in 1942. Etymology The fault is named after Ibagué, the capital of Tolima.Diederix et al., 2006, p.492 Description The Ibagué Fault crosses the central part and eastern slope of the Central Ranges of the Colombian Andes, close to the city of Ibagué. The fault strikes west-southwest to east-northeast, controlling the course of the Cocora River. The fault has a well developed fault trace with prominent linear fault ridges (whale backs) as much as long and high, fault scarplets aligned with ridges, sag ...

Ibagué
Ibagué () (referred to as San Bonifacio de Ibagué del Valle de las Lanzas during the Spanish period) is the capital of Tolima, one of the 32 departments that make up the Republic of Colombia. The city is located in the center of the country, on the central mountain range of the Colombian Andes, near Nevado del Tolima. It is one of the most populous cities in the country, with about 529,635 (according to the 2018 census) inhabitants, making it the seventh (7th) most populous in Colombia. It was founded on October 14, 1550, by the Spanish captain Andrés López de Galarza. The city of Ibagué is divided into 13 communes and the rural area has 17 corregimientos. As the capital of the department of Tolima the city hosts the Government of Tolima, the Departmental Assembly, and the Attorney General's Office. It is the main epicenter of political, economic, administrative, business, art, culture, and tourism activities in the area. Ibagué maintains one of the major urban econo ...

Departments Of Colombia
Colombia is a unitary republic made up of thirty-two departments ( Spanish: ''departamentos'', sing. '' departamento'') and a Capital District ('' Distrito Capital''). Each department has a governor (''gobernador'') and an Assembly (''Asamblea Departamental''), elected by popular vote for a four-year period. The governor cannot be re-elected in consecutive periods. Departments are country subdivisions and are granted a certain degree of autonomy. Departments are formed by a grouping of municipalities (''municipios'', sing. '' municipio''). Municipal government is headed by mayor (''alcalde'') and administered by a municipal council (''concejo municipal''), both of which are elected for four-year periods. Some departments have subdivisions above the level of municipalities, commonly known as provinces.

Transpression
In geology, transpression is a type of strike-slip deformation that deviates from simple shear because of a simultaneous component of shortening perpendicular to the fault plane. This movement ends up resulting in oblique shear. It is generally very unlikely that a deforming body will experience "pure" shortening or "pure" strike-slip. The relative amounts of shortening and strike-slip can be expressed in the convergence angle alpha which ranges from zero (ideal strike-slip) to 90 degrees (ideal convergence). During shortening, unless material is lost, transpression produces vertical thickening in the crust. Transpression that occurs on a regional scale along plate boundaries is characterized by oblique convergence. More locally, transpression occurs within restraining bends in strike-slip fault zones. Transpressional structures Transpressional shear zones are characterized by an association of structures that suggest zone-normal shortening and zone-parallel shearing. Commonly ...

Bucaramanga-Santa Marta Fault
The Bucaramanga-Santa Marta Fault (BSMF, BSF) or Bucaramanga-Santa Marta Fault System ( es, (Sistema de) Falla(s) de Bucaramanga-Santa Marta) is a major oblique transpressional sinistral strike-slip fault (wrench fault) in the departments of Magdalena, Cesar, Norte de Santander and Santander in northern Colombia. The fault system is composed of two main outcropping segments, named Santa Marta and Bucaramanga Faults, and an intermediate Algarrobo Fault segment in the subsurface. The system has a total length of and runs along an average north-northwest to south-southeast strike of 341 ± 23 from the Caribbean coast west of Santa Marta to the northern area of the Eastern Ranges of the Colombian Andes. The fault system is a major bounding fault for various sedimentary basins and igneous and metamorphic complexes. The northern Santa Marta Fault segment separates the Sinú-San Jacinto Basin and Lower Magdalena Valley in the west from the Sierra Nevada de Santa Marta to the east. ...

Murindó Fault
The Murindó Fault ( es, Falla Murindó) is a strike-slip fault in the department of Antioquia and Chocó in northwestern Colombia. The fault has a total length of and runs along an average north-northwest to south-southeast strike of 347.4 ± 6 in the Chocó Basin along the western edge of the Western Ranges of the Colombian Andes. Etymology The fault is named after Murindó.Paris et al., 2000, p.14 Description The fault in the Chocó Basin extends along the western slope of the Western Ranges of the Colombian Andes, from the Arquia River in the south to the Río Sucio and the basin of the Atrato River in the north. The Murindó Fault places Cretaceous volcanic (basic) rocks against Tertiary turbidites, and crosscuts Tertiary quartz-diorite and granodiorite. The Murindó River flows along the Murindó Fault near Murindó.Plancha 113, 2007 The fault underlies the municipalities of Dabeiba and Frontino.Plancha 128, 2002 To the south, the fault runs parallel to the ...

Romeral Fault System
The Romeral Fault System ( es, Sistema de Fallas (de) Romeral) is a megaregional system of major parallel and anastomosing faults in the Central Ranges of the Colombian Andes and the Cauca, Amagá, and Sinú-San Jacinto Basins. The system spans across ten departments of Colombia, from northeast to south Bolívar, Sucre, Córdoba, Antioquia, Caldas, Risaralda, Quindío, Valle del Cauca, Cauca and Nariño. The fault zone extends into Ecuador where it is known as the Peltetec Fault System. The in detail described part of the Romeral Fault System south of Córdoba has a total length of with a cumulative length of and runs along an average north to south strike of 017.6 ± 16, cross-cutting the central-western portion of Colombia. The fault system, active during more than 200 million years from the Triassic to recent, represents the ancient western continental margin of northwestern South America and forms the boundary between obducted oceanic crust to the west of the f ...

Cucuana Fault
The Cucuana Fault ( es, Falla Cucuana) is a dextral strike-slip fault in the departments of Tolima and Cundinamarca in Colombia. The fault has a total length of and runs along an average east-northeast to west-southwest strike of 067.9 ± 6 crossing the Middle Magdalena Valley from the Central towards the Eastern Ranges of the Colombian Andes. Etymology The fault is named after the Cucuana River.Paris et al., 2000a, p.49 Description The Cucuana Fault is parallel to and south of the Ibagué Fault in the Central Ranges of the Colombian Andes, crossing Paleozoic metamorphic rocks, Mesozoic igneous rocks (Ibagué Batholith), and Tertiary beds. The fault extends into the Eastern Ranges across the Middle Magdalena Valley, cutting Cretaceous beds. The Quaternary sedimentary and volcanic fill of the Magdalena River valley is not reported as having been deformed by the fault. This fault has a prominent trace on satellite images. It has displaced drainages, spurs, fault s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magdalena River
The Magdalena River ( es, Río Magdalena, ; less commonly ) is the main river of Colombia, flowing northward about through the western half of the country. It takes its name from the biblical figure Mary Magdalene. It is navigable through much of its lower reaches, in spite of the shifting sand bars at the mouth of its delta, as far as Honda, at the downstream base of its rapids. It flows through the Magdalena River Valley. Its drainage basin covers a surface of , which is 24% of the country's area and where 66% of its population lives. Course The Magdalena River is the largest river system of the northern Andes, with a length of 1,612 km. Its headwaters are in the south of Colombia, where the Andean subranges Cordillera Central and Cordillera Oriental separate, in Huila Department. The river runs east then north in a great valley between the two cordilleras. It reaches the coastal plain at about nine degrees north, then runs west for about , then north again, reaching ...
