1996 Nazca Earthquake
The 1996 Nazca earthquake occurred on November 12 at 16:59 UTC (11:59 local time). The earthquake was located offshore near Nazca, Peru. It has a magnitude of 7.7. Fourteen people were reported dead. Four-thousand houses collapsed and 11,000 were partially damaged. Nazca and Acarí were the most affected cities. Liquefaction was observed in the bed of the Yauca River. The intensity was VIII (''Severe'') in Nazca. A tsunami was triggered by this earthquake. The recorded peak-to-trough heights of the tsunami were 25 cm in Callao, Peru and 35 cm in Arica, Chile. In this area, the Nazca Plate is subducting beneath the South American Plate. This earthquake occurred at the plate interface and is associated with the subduction of the 1.5 km high Nazca Ridge beneath the South American plate. This was a complex event, and there were at least two larger events occurring between 18 and 30 seconds after the onset. This earthquake may have ruptured part of the rupture zone of ...

Nazca
Nazca (; sometimes spelled Nasca; qu, Naska) is a city and system of valleys on the southern coast of Peru. It is also the name of the largest existing town in the Nazca Province. The name is derived from the Nazca culture, which flourished in the area between 100 BC and AD 800. This culture was responsible for the Nazca Lines and the ceremonial city of Cahuachi. They also constructed additional underground aqueducts, named puquios, in a regional system that still functions today. The first puquios are believed to have been built by the preceding Paracas culture. Nazca is the capital of the Nazca Province located in the Ica District of the Ica region of Peru. Earthquake On November 12, 1996, at 11:59 a.m. local time (16:59 GMT) there was an earthquake of magnitude 7.5 with its epicenter at 7.7 km into the sea. The earthquake almost completely destroyed the city of Nazca and its surroundings. Due to its occurrence during the day, there were only 14 fatalities. Ho ...

Nazca Ridge
The Nazca Ridge is a submarine ridge, located on the Nazca Plate off the west coast of South America. This plate and ridge are currently subducting under the South American Plate at a convergent boundary known as the Peru-Chile Trench at approximately per year. The Nazca Ridge began subducting obliquely to the collision margin at 11°S, approximately 11.2 Ma, and the current subduction location is 15°S. The ridge is composed of abnormally thick basaltic ocean crust, averaging 18 ±3 km thick. This crust is buoyant, resulting in flat slab subduction under Peru. This flat slab subduction has been associated with the uplift of Pisco Basin and the cessation of Andes volcanism and the uplift of the Fitzcarrald Arch on the South American continent approximately 4 Ma. Morphology The Nazca Ridge is approximately wide, long, and has of bathymetric relief. The gradient of the slopes is 1-2 degrees. The ridge is located at a depth of below sea level, above the carbonate com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquakes In Peru
Earthquakes in Peru are common occurrences as the country is located in a seismic zone. The interface between the Nazca and South American tectonic plates is located near the Peruvian coast. The South American Plate is moving over the Nazca Plate at a rate of per year. This earthquakes occur as thrust faulting on the interface between the two plates, with the South American Plate moving towards the sea over the Nazca Plate. The same process has caused the rise of the Andes mountain range and the creation of the Peru–Chile Trench, as well as volcanism in the Peruvian highlands. Geology of Peru The oldest rocks in Peru date to the Precambrian and are more than two billion years old. Along the southern coast, granulite and charnockite shows reworking by an ancient orogeny mountain-building event. Situated close to the Peru-Chile Trench, these rocks have anomalously high strontium isotope ratios, which suggest recent calc-alkaline volcanism. In the Eastern Cordillera of Peru, Pr ...

1942 Peru Earthquake
The 1942 Peru earthquake occurred on August 24 at and was located near the border of the departments of Ica and Arequipa, Peru. It had a magnitude of 8.2 or 8.4. Earthquake This is a megathrust earthquake which ruptured part of the boundary between the Nazca Plate and the South American Plate. In this area, the Nazca Plate is subducting beneath the South America Plate with a convergence vector of about 7.6 cm/yr. Much of the rupture zone of the 1942 earthquake overlapped with that of the 1996 Nazca earthquake. The rupture zone of the 1942 earthquake was about 40 km longer than that of the 1996 earthquake. The epicenter of the 1942 earthquake was very close to, but slightly southeast of, that of the 1996 earthquake. The energy released by the 1942 earthquake was about 2.5×1017 Nm. Damage The earthquake caused 30 deaths and 25 injuries. Building damage was noteworthy in the epicentral area. About 30% of the buildings in the city of Nazca were ruined. There were sl ...

South American Plate
The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge. The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the oceanic crust of the North American Plate. At the Chile Triple Junction, near the west coast of the Taitao–Tres Montes Peninsula, an oceanic ridge known as the Chile Rise is actively subducting under the South American Plate. Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: "Parts of the plate boundaries consisting of alternations of relati ...

Nazca Plate
The Nazca Plate or Nasca Plate, named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction, along the Peru–Chile Trench, of the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise and the Chile Rise respectively. The movement of the Nazca Plate over several hotspots has created some volcanic islands as well as east-west running seamount chains that subduct under South America. Nazca is a relatively young plate both in terms of the age of its rocks and its existence as an independent plate having been formed from the break-up of the Farallon Plate about 23 million years ago. The oldest rocks of the plate are about 50 million years old. Boundaries East Pacific and Chile Rise A triple junctio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
