Honda Fault
The Honda Fault ( es, Falla de Honda is a reverse sinistral oblique strike-slip fault in the departments of Tolima, Caldas and Cundinamarca in central Colombia. The fault has a total length of and runs along an average north-northeast to south-southwest strike of 016.6 ± 12 in the Middle Magdalena Valley. Etymology The fault is named after Honda, Tolima.Paris et al., 2000, p.32 Description The Honda Fault extends through the Middle Magdalena Valley, close to the Magdalena River and the cities of Ambalema, Honda, and La Dorada. It offsets beds of the Miocene Honda Group, Pliocene Mesa Formation, and Quaternary sediment in alluvial terraces. The fault trace is characterised by continuous prominent scarps, aligned drainages, fault saddles, linear ridges and valleys, sag ponds, degraded scarps, and localized uplifts. The southern half of the fault has a very low to low slip rate (less than per year), while the northern half is low to medium at per year. See also ...

Honda, Tolima
Honda is a town and municipality in the Tolima department of Colombia. The population of the municipality was 23,616 as of the census 2018. Along with Líbano, Honda is the seat of the Roman Catholic Diocese of Líbano-Honda. The main industries of Honda are tourism, fishing, and cattle-ranching.

Geography Of Caldas Department
Geography (from Ancient Greek, Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and world, its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the Tobler's first law of geography, first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thrust Faults
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or ''window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular ''klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind thr ...

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 ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California.

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 ...

Fault Scarp
A fault scarp is a small step or offset on the ground surface where one side of a fault has moved vertically with respect to the other. It is the topographic expression of faulting attributed to the displacement of the land surface by movement along faults. They are exhibited either by differential movement and subsequent erosion along an old ''inactive'' geologic fault (a sort of old rupture), or by a movement on a recent active fault. Characteristics Fault scarps often contain highly fractured rock of both hard and weak consistency. In many cases, bluffs form from the upthrown block and can be very steep. The height of the scarp formation is equal to the vertical displacement along the fault. Active scarps are usually formed by tectonic displacement, e.g. when an earthquake changes the elevation of the ground and can be caused by any type of fault, including strike-slip faults, whose motion is primarily horizontal. This movement is usually episodic, with the height of the bluf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
