Earthquakes In Ecuador
This list of earthquakes in Ecuador is a list of notable earthquakes that have affected Ecuador in recorded history. Tectonic setting The active tectonics of Ecuador is dominated by the effects of the subduction of the Nazca Plate beneath the South American Plate. Ecuador lies within the Northern Volcanic Zone where the subduction zone is moving at a rate of 7 cm/yr to the east-northeast, significantly oblique to the trend of this segment of the Andes. The subduction zone has an overall dip of 25–30°, but varies rapidly along strike due to the effects of subduction of the Carnegie Ridge. The Carnegie Ridge is an oceanic plateau that formed as the Nazca Plate passed over the Galapagos hotspot. The plate interface above the subducted part of the ridge has a shallower dip than the area to both north and south, the boundaries interpreted to consist of two large tears in the downgoing Nazca Plate. The northern part of Ecuador overlies the subducted part of the Carnegie Ridg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), 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. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 south of Ecuador's capital Quito and located 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. He a ...

1979 Tumaco Earthquake
The 1979 Tumaco earthquake occurred at on 12 December with a moment magnitude of 8.2 and a maximum Mercalli intensity of IX (''Violent''). The epicenter was just offshore from the border between Ecuador and Colombia, near the port city of Tumaco. It triggered a major tsunami, which was responsible for most of the estimated 300–600 deaths. The hardest hit area was Colombia's Nariño Department. Tectonic setting Coastal parts of Ecuador and southern Colombia lie above the convergent boundary where the Malpelo Plate subducts beneath the South American Plate along the Colombia–Ecuador Trench. At this location the Malpelo Plate, the microplate northeast of the Nazca Plate, is moving to the east relative to South America at a rate of 58 mm per year. North of the Carnegie Ridge, the subduction interface has four recognisable segments, from south to north, the Esmeraldas, Manglares, Tumaco and Patia segments. This plate boundary has been the location of several great histori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

El Oro Province
El Oro (; ''oro'' = gold) is the southernmost of Ecuador's coastal provinces. It was named for its historically important gold production. Today it is one of the world's major exporters of bananas. The capital is Machala. History The area was settled by the Inca, who inhabited the area at the time Spanish settlement began in 1549. The Spanish found gold there and mined it, carrying the gold to Spain. The province was named for its historically important gold production. The gold was mined by the Spanish mainly in the late 16th and 17th centuries in the village of Zaruma in the Zaruma Canton. In the 18th century, the earthquake of January 1749 destroyed the mining area. A local rebellion stopped the mining until the Spanish agreed to allow the native people to benefit from the mining. Spain imported gold from the area until the area gained its independence from Spain in 1820. Philip II of Spain granted the village the title of "Villa de Sant Antonio del Zerro de Oro de Zaruma" ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970 Peru–Ecuador Earthquake
The 1970 Peru–Ecuador earthquake occurred on December 9 at . The epicenter was located in northwestern Peru, between Piura and Tumbes, near the Peru–Ecuador border. This earthquake had a magnitude of 7.1, or 7.1. About 81 people were reported dead in Peru and in Ecuador together. Liquefaction was observed. The maximum Mercalli Intensity reached IX (''Violent''). Fractures in constructions were reported in the urban area of Talara. This was a shallow earthquake, and it was thought to occur in the plate above the plate boundary.

1958 Ecuador–Colombia Earthquake
The 1958 Ecuador–Colombia earthquake struck the coastal regions of Ecuador and Colombia on January 19 with a surface wave magnitude of 7.6 at 9:07 local time. Approximately 30 percent of Esmeraldas (Ecuador) was destroyed, including the children's department of the hospital, where three children died. In all, 111 persons died and 45 were injured as a result of the earthquake. Water mains were broken and power transmission lines were damaged. The Esmeraldas- Quito highway collapsed at many places. Many other roads of the country were made impassable by cracks and fallen trees. According to press reports, a landslide from the slopes of the Andes at Panado village buried a hundred people. The earthquake was destructive in the cities on the northern coast of the country and was strong from Latacunga to Quito, Ibarra and Tulcán. It was felt at Guayaquil.

1953 Tumbes Earthquake
The 1953 Tumbes earthquake occurred on December 12 at near the border between Peru and Ecuador. The shock had a moment magnitude of 7.5, a maximum Mercalli Intensity of VIII (''Severe''), and occurred in the northwestern offshore area of Tumbes, Peru. Geology The North Andean convergent margin is a region of large crustal deformation. The North Andes block moves northeastwards relative to the South America at a rate of 6±2 mm/yr. The Nazca Plate is subducting beneath the South American Plate along the Colombia-Ecuador Trench. The subduction of the Carnegie Ridge into the Colombia-Ecuador Trench affected the crustal deformation in this region and the coupling between the Nazca Plate and the South America Plate. In addition, the subduction of the Carnegie Ridge may be an important drive contributing to the relatively northeastward movement of the North Andes block. Although there was no large earthquakes in the Gulf of Guayaquil segment of the subduction zone in the late 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambato, Ecuador
Ambato (; full form, San Juan de Ambato; Quechua: Ampatu Llaqta) is a city located in the central Andean valley of Ecuador. Lying on the banks of the Ambato River, the city also sits beneath several tall mountains. It is the Tungurahua province capital city Tungurahua, at an elevation of 2,577 meters above sea level. It is variously nicknamed "City of Flowers and Fruits", "Land of the Three Juan's", and "Garden of Ecuador." Ambato's inhabitants are called Ambateños or Guaytambos (after a type of native peach that the valley is famous for producing). The current mayor of Ambato is Javier Altamirano. The city has been fully or partially destroyed by earthquakes several times in its history, most recently on 5 August 1949, when the city and its cathedral were almost completely devastated. The city was rebuilt in the following two years. In honour of the tenacity of their residents, Ambato celebrates "The Festival of Fruits and Flowers" during Carnival in February. Today, the F ...

1942 Ecuador Earthquake
The 1942 Ecuador earthquake or the Guayaquil earthquake occurred on 13 May at 9:06 or 9:13 pm local time with a moment magnitude of 7.9. The temblor struck the coastal ( Esmeraldas) region of Manabí Province, Ecuador. It caused damage mainly to cities like Guayaquil, Portoviejo and Guaranda. More than 300 people were killed and the total cost of damage was about US$2.5 million (1942 rate). Ecuador's largest city Guayaquil was the most affected despite the significant distantce from the epicenter. Many reinforced concrete structures in a particular area in the city were completely destroyed, contributing to fatalities. Tectonic setting The Nazca Plate dives beneath the South American Plate along a convergent plate boundary stretching from Colombia to Chile in a process known as subduction. This plate boundary occasionally produces large megathrust earthquakes along the west coast of South America. The Ecuador–Colombia subduction zone occupies part of this plate boundary, where ...
