1949 Ambato Earthquake
The 1949 Ambato earthquake was the deadliest earthquake in the Western Hemisphere in five years. On August 5, 1949, it struck Ecuador's Tungurahua Province southeast of its capital Ambato and killed 5,050 people. Measuring 6.4 on the scale, it originated from a hypocenter 15 km beneath the surface. The nearby villages of Guano, Patate, Pelileo, and Pillaro were destroyed, and the city of Ambato suffered heavy damage. The earthquake flattened buildings and subsequent landslides caused damage throughout the Tungurahua, Chimborazo, and Cotopaxi Provinces. It disrupted water mains and communication lines and opened a fissure into which the small town of Libertad sank. Moderate shaking from the event extended as far away as Quito and Guayaquil. Earthquakes in Ecuador stem from two major interrelated tectonic areas: the subduction of the Nazca Plate under the South American Plate and the Andean Volcanic Belt. The 1949 Ambato earthquake initially followed an intersection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambato, Ecuador
Ambato (; full form, San Juan de Ambato; Quechuan languages, Quechua: Ampatu Llaqta) is a city located in the central Andes, Andean valley of Ecuador. Lying on the banks of the Ambato River (Ecuador), Ambato River, the city also sits beneath several tall mountains. It is the Tungurahua province capital city Tungurahua Province, 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 1949 Ambato earthquake, 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, Ambat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2007 Peru Earthquake
The 2007 Peru earthquake, which measured 8.0 on the moment magnitude scale, hit the central coast of Peru on August 15 at 23:40:57 UTC (18:40:57 local time) and lasted two minutes. The epicenter was located south-southeast of Lima at a depth of . The United States Geological Survey National Earthquake Information Center reported that it was a ''Very strong'' earthquake. The Peruvian government stated that 519 people were killed by the quake. Earthquake This earthquake occurred at the boundary between the Nazca and South American tectonic plates, which are converging at a rate of per year. The earthquake occurred as thrust faulting on the interface between the two plates, with the South American Plate moving up and seaward over the Nazca Plate. Experts say this kind of earthquake is produced about once every 100 years. Coastal Peru has a history of very large earthquakes. The August 15th shock originated near the source of two previous earthquakes, both in the magnitude 8 rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2016 Ecuador Earthquake
The 2016 Ecuador earthquake occurred on April 16 at with a moment magnitude of 7.8 and a maximum Mercalli intensity of VIII (''Severe''). The very large thrust earthquake was centered approximately from the towns of Muisne and Pedernales in a sparsely populated part of the country, and from the capital Quito, where it was felt strongly. Regions of Manta, Pedernales and Portoviejo accounted for over 75 percent of total casualties. Manta's central commercial shopping district, Tarqui, was completely destroyed. Widespread damage was caused across Manabí Province, with structures hundreds of kilometres from the epicenter collapsing. At least 676 people were killed and 16,600 people injured. President Rafael Correa declared a state of emergency; 13,500 military personnel and police officers were dispatched for recovery operations. Geology Ecuador lies above the destructive plate boundary where the Nazca Plate is subducting beneath the South American Plate. The co ...

1987 Ecuador Earthquakes
The 1987 Ecuador earthquakes occurred over a six-hour period on March 6. The sequence of shocks measured 6.7, 7.1, and 6.0 on the moment magnitude scale. The main shock had a maximum Mercalli intensity of IX (''Violent''). The earthquakes were centered in Napo Province in northeast Ecuador; the epicenters were on the eastern slopes of the Andes, about 75 km ENE of Quito and 25 km north of Reventador Volcano. The earthquakes caused about 1,000 deaths. Four thousand were missing and an estimated US$1 billion in damage was caused.

Life (magazine)
''Life'' was an American magazine published weekly from 1883 to 1972, as an intermittent "special" until 1978, and as a monthly from 1978 until 2000. During its golden age from 1936 to 1972, ''Life'' was a wide-ranging weekly general-interest magazine known for the quality of its photography, and was one of the most popular magazines in the nation, regularly reaching one-quarter of the population. ''Life'' was independently published for its first 53 years until 1936 as a general-interest and light entertainment magazine, heavy on illustrations, jokes, and social commentary. It featured some of the most notable writers, editors, illustrators and cartoonists of its time: Charles Dana Gibson, Norman Rockwell and Jacob Hartman Jr. Gibson became the editor and owner of the magazine after John Ames Mitchell died in 1918. During its later years, the magazine offered brief capsule reviews (similar to those in ''The New Yorker'') of plays and movies currently running in New York City, bu ...

1944 San Juan Earthquake
The 1944 San Juan earthquake took place in the province of San Juan, in the center-west area of Argentina, a region highly prone to seismic events. This moderate to strong earthquake (estimated moment magnitudes range from 6.7 to 7.8) destroyed a large part of San Juan, the provincial capital, and killed 10,000 of its inhabitants, 10% of its population at the time. One third of the province population became homeless. It is acknowledged as the worst natural disaster in Argentine history. The earthquake occurred at 8:52 pm on 15 January 1944 and had its epicenter located 30 km north of the provincial capital, near La Laja in Albardón Department. Some 90% of the buildings in the city were destroyed and those left standing suffered such damage that in most cases they had to be demolished. It is considered that the reason for such widespread destruction was the low quality of construction, rather than just the power of the earthquake. In 1944 many of San Juan's houses were ...

1797 Riobamba Earthquake
The 1797 Riobamba earthquake occurred at 12:30 UTC on 4 February. It devastated the city of Riobamba and many other cities in the Interandean valley, causing between 6,000–40,000 casualties. It is estimated that seismic intensities in the epicentral area reached at least XI (''Extreme'') on the Mercalli intensity scale, and that the earthquake had a magnitude of 7.6–8.3, the most powerful historical event known in Ecuador. The earthquake was studied by Prussian geographer Alexander von Humboldt, when he visited the area in 1801–1802. Tectonic setting The active tectonics of Ecuador is dominated by the effects of the subduction of the Nazca Plate beneath the South American Plate. The main NNE-SSW trending fault systems show a mixture of dextral (right lateral) strike-slip faulting and reverse faulting. In addition to these faults that run parallel to the Andes in Ecuador, there are two important SW-NE trending-dextral-fault systems: the Pallatanga fault and the Chingual f ...

Intraplate Earthquake
The term intraplate earthquake refers to a variety of earthquake that occurs ''within the interior'' of a tectonic plate; this stands in contrast to an interplate earthquake, which occurs ''at the boundary'' of a tectonic plate. Intraplate earthquakes are often called "intraslab earthquakes", especially when occurring in microplates. Intraplate earthquakes are relatively rare compared to the more familiar boundary-located interplate earthquakes. Structures far from plate boundaries tend to lack seismic retrofitting, so large intraplate earthquakes can inflict heavy damage. Examples of damaging intraplate earthquakes are the devastating Gujarat earthquake in 2001, the 2012 Indian Ocean earthquakes, the 2017 Puebla earthquake, the 1811–1812 earthquakes in New Madrid, Missouri, and the 1886 earthquake in Charleston, South Carolina. Fault zones within tectonic plates The surface of the Earth is made up of seven primary and eight secondary tectonic plates, plus dozens of terti ...

Interplate Earthquake
An interplate earthquake is an earthquake that occurs at the boundary between two tectonic plates. Earthquakes of this type account for more than 90 percent of the total seismic energy released around the world. If one plate is trying to move past the other, they will be locked until sufficient stress builds up to cause the plates to slip relative to each other. The slipping process creates an earthquake with relative displacement on either side of the fault, resulting in seismic waves which travel through the Earth and along the Earth's surface. Relative plate motion can be lateral as along a transform fault boundary, vertical if along a convergent boundary (i.e. subduction or thrust/reverse faulting) or a divergent boundary (i.e. rift zone or normal faulting), and oblique, with horizontal and lateral components at the boundary. Interplate earthquakes associated at a subduction boundary are called megathrust earthquakes, which include most of the Earth's largest earthquakes. Intra ...

Carnegie Ridge
The Carnegie Ridge is an aseismic ridge on the Nazca Plate that is being subducted beneath the South American Plate. The ridge is thought to be a result of the passage of the Nazca Plate over the Galapagos hotspot. It is named for the research vessel '' Carnegie'', which discovered it in 1929. Extent The Carnegie Ridge is seen to extend eastwards over 1,000 km from the Galapagos islands to the Colombia-Ecuador trench and is interpreted to continue beneath northern Ecuador for about a further 700 km. The subducted extent is disputed, with some workers arguing that there is no evidence of a subducted ridge beneath Ecuador extending more than about 60 km from the trench. Structure The Carnegie Ridge consists of thickened oceanic crust. Wide-angle seismic reflection and refraction data acquired over the central and eastern part of the ridge give crustal thicknesses of 13 km and 19 km respectively for crust that has estimated ages of about 11 Ma and 20 Ma. ...

Andean Volcanic Belt
The Andean Volcanic Belt is a major volcanic belt along the Andean cordillera in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is formed as a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones which are separated by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products, and morphology. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences within volcanic zones and even between neighboring volcanoes. Despite being a type location for calc-alkalic and subduction volcanism, the Andean Volcanic Belt has a broad range of volcano-tectonic settings, as it has rift systems and extensional zones, transpressional faults, subduction of mid-ocean ridges and seamount chains as well as a large range of crustal thicknesses and magma ascent paths and different amounts of crustal assim ...
