1698 Ambato Earthquake
The 1698 Ambato earthquake affected the interior of Ecuador on 20 June at 01:00 local time. The earthquake seismic magnitude () ranged from 7.2 to 7.9. Damage was widespread and extreme in the provinces of Tungurahua Province, Tungurahua, Cotopaxi Province, Cotopaxi and Chimborazo Province, Chimborazo. The earthquake also triggered mudflows along the Ambato River (Ecuador), Ambato River destroying a city and killing many residents. An estimated 6,500 fatalities were attributed to the shock and thousands more from the landslides. Tectonic setting Central Ecuador features the north Andes mountains which formed by subduction of the Pacific plate beneath the South American plate. Subduction occurs off the coast of Ecuador and Colombia at an Oblique subduction, oblique angle. This results in crustal deformation inland within the Andes mountains, pushing a tectonic block within the South American plate northeast. This tectonic block, known as the North Andes plate, is bounded by subduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuador
Ecuador, officially the Republic of Ecuador, is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. It also includes the Galápagos Province which contains the Galapagos Islands in the Pacific, about west of the mainland. The country's Capital city, capital is Quito and its largest city is Guayaquil. The land that comprises modern-day Ecuador was once home to several groups of Indigenous peoples in Ecuador, indigenous peoples that were gradually incorporated into the Inca Empire during the 15th century. The territory was Spanish colonization of the Americas, colonized by the Spanish Empire during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as a sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its million people being mestizos, followed by large minorities of Europe ...

Epicenter
The epicenter (), epicentre, or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Determination The primary purpose of a seismometer is to locate the initiating points of earthquake epicenters. The secondary purpose, of determining the 'size' or magnitude must be calculated after the precise location is known. The earliest seismographs were designed to give a sense of the direction of the first motions from an earthquake. The Chinese frog seismograph would have dropped its ball in the general compass direction of the earthquake, assuming a strong positive pulse. We now know that first motions can be in almost any direction depending on the type of initiating rupture ( focal mechanism). The first refinement that allowed a more precise determination of the location was the use of a time scale. Instead of merely noting, or recording, the absolute motions of ...

Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand. One such example of this is aragonite, which has been created over the past 500million years by various forms of life, such as coral and shellfish. It is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, as in the Caribbean. Somewhat more rarely, sand may be composed ...

Tungurahua
Tungurahua (; from Quichua ''tunguri'' (throat) and ''rahua'' (fire), "Throat of Fire")) is an active stratovolcano located in the Cordillera Oriental of Ecuador. The volcano gives its name to the province of Tungurahua. Volcanic activity restarted on August 19, 1999, and is ongoing , with several eruptive episodes since then, the most recent lasting from February 26 to March 16, 2016. Etymology According to one theory the name ''Tungurahua'' is a combination of the Quichua ''tunguri'' (throat) and ''rahua'' (fire) meaning "Throat of Fire". According to another theory it is based on the Quichua ''uraua'' for crater. Tungurahua is also known as "The Black Giant" (''Gigante Negro'' in spanish), and in local indigenous mythology it is referred to as ''Mama Tungurahua'' ("Mother Tungurahua"). Geography and geology Location Tungurahua is located in the Cordillera Oriental of the Andes of central Ecuador, south of the capital Quito. Nearby notable mountains are Chimbor ...

Riverbank
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking downstream; a well-known example of this being the southern left bank and the northern right bank of the river Seine defining parts of Paris. The shoreline of ponds, swamps, estuaries, reservoirs, or lakes are also of interest in limnology and are sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riverbed
A streambed or stream bed is the bottom of a stream or river and is confined within a Stream channel, channel or the Bank (geography), banks of the waterway. Usually, the bed does not contain terrestrial (land) vegetation and instead supports different types of aquatic vegetation (aquatic plant), depending on the type of streambed material and water velocity. Streambeds are what would be left once a stream is no longer in existence. The beds are usually well preserved even if they get buried because the banks and canyons made by the stream are typically hard, although soft sand and debris often fill the bed. Dry, buried streambeds can actually be underground water pockets. During times of rain, sandy streambeds can soak up and retain water, even during dry seasons, keeping the water table close enough to the surface to be obtainable by local people. The nature of any streambed is always a function of the flow dynamics and the local geologic materials. The climate of an area wil ...

Landslide
Landslides, also known as landslips, rockslips or rockslides, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Landslides are frequently made worse by human development (such as urban sprawl) and resource exploitation (such as mining and deforestation). Land degradation freque ...

Riobamba
Riobamba (, full name San Pedro de Riobamba; Quechua: ''Rispampa'') is the capital of Chimborazo Province in central Ecuador, and is located in the Chambo River Valley of the Andes. It is located south of Ecuador's capital Quito and situated at an elevation of 2,754 m. The city is an important regional transport center and a stop on the Pan-American Highway, which runs through Ecuador. Riobamba is one of the largest cities in the central portion of Ecuador's Sierra region. Name Riobamba takes its name from a combination of ''rio'', the Spanish word for "river", and ''rispampa'', the Quechua word for "plain." History The region surrounding Riobamba was inhabited by the Puruhá nation before the advance of the Inca Empire during the late 15th century. The Puruha fiercely resisted the Inca efforts to conquer the north of today's Ecuador. The Inca Huayna Capac had to make an alliance in order to pacify the tribes who sided with Condorazo, the general of the Puruha nation ...

Latacunga
Latacunga (; Quechua: Latakunga) is a plateau city of Ecuador, capital of the Cotopaxi Province, south of Quito, near the confluence of the Alaquez and Cutuchi rivers to form the Patate, the headstream of the Pastaza. At the time of census 2022 Latacunga had a population of 77,267 largely mestizo and indigenous. Latacunga took its independence from Spain on November 11, 1820. Latacunga is an hour and half south from Quito on the Pan-American Highway. It was previously also on the old road from Quito to Guayaquil, and has a railway station between those cities. It is 9, 383. 2 ft (2,860 m). above sea level. Its climate is cold and windy, due to the neighboring snowclad heights, and the barren, pumice-covered tableland on which it stands. The active volcano Cotopaxi is only away, and the town has suffered repeatedly from eruptions. Founded in 1534, it was four times destroyed by earthquakes between 1698 and 1798. The neighboring ruins of an older native town are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
