2010 Pichilemu Earthquake
The 2010 Pichilemu earthquakes ( es, link=no, Terremoto de Pichilemu de 2010), also known as the Libertador O'Higgins earthquakes, were a pair of intraplate earthquakes measuring 6.9 and 7.0 that struck Chile's O'Higgins Region on 11 March 2010 about 16 minutes apart. The earthquakes were centred northwest of the city of Pichilemu. The earthquakes were caused by increased regional stress arising from an earthquake on 27 February, centered offshore Maule Region, which was felt throughout central Chile. The Hawaii-based Pacific Tsunami Warning Center pointed out the possibility of local tsunamis within of the epicentre, although small, but violent waves were seen in the Pichilemu and Bucalemu area. One person was reported dead. At least eleven aftershocks immediately followed, causing panic throughout coastal towns between the Coquimbo and Los Lagos regions. The earthquakes were especially destructive in the epicentre town, Pichilemu, capital of Cardenal Caro Province. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epicentre
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. Surface damage Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in the magnitude 7.9 Denali earthquake of 2002 in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from . Continental earthquakes below are rare whereas in subduction zone earthquakes can originate at depths deeper than . Epicentral distance During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite s ...

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] |
Convergent Boundary
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more Plate tectonics, lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, Orogeny, orogenesis, destruction of lithosphere, and Deformation (geology), deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by the radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surfac ...

Plaza Arturo Prat Y Quioscos Después
A town square (or square, plaza, public square, city square, urban square, or ''piazza'') is an open public space, commonly found in the heart of a traditional town but not necessarily a true geometric square, used for community gatherings. Related concepts are the civic center, the market square and the village green. Most squares are hardscapes suitable for open markets, concerts, political rallies, and other events that require firm ground. Being centrally located, town squares are usually surrounded by small shops such as bakeries, meat markets, cheese stores, and clothing stores. At their center is often a well, monument, statue or other feature. Those with fountains are sometimes called fountain squares. By country Australia The city centre of Adelaide and the adjacent suburb of North Adelaide, in South Australia, were planned by Colonel William Light in 1837. The city streets were laid out in a grid plan, with the city centre including a central public square, Victo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agustín Ross Cultural Centre
Agustín Ross Cultural Centre (Spanish, '' Centro Cultural Agustín Ross''), previously known as Casino Ross (''Ross Casino''), is the cultural center of the city of Pichilemu in Libertador General Bernardo O'Higgins Region, Chile. It was constructed between 1906 and 1909 at the request of politician Agustín Ross Edwards. The structure of the cultural center is very similar to that of the Grand Trianon in Versailles, France. It is best known for housing one of the first casinos of Chile; a casino operated in the building between 1917 and 1931. After 1931 all casinos, except the newly opened Casino de Viña del Mar, were declared illegal. The building has also been used as a post office, a store selling imported goods, a hotel, a discotheque, and a bar. There were two attempts by the local government to purchase the building; the first time in 1982 failed while the second in 1995 succeeded. The former casino was declared a National Monument of Chile along with the Agustín Ross ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agustín Ross Park
Agustín Ross Park ( es, Parque Agustín Ross) is a park located in the Agustín Ross Avenue, in front of the old Ross Casino, in Pichilemu. It is a National Monument of Chile. The original park contains 100-year-old native Canary Island Date palms (''Phoenix canariensis ''Phoenix canariensis'', the Canary Island date palm or pineapple palm, is a species of flowering plant in the palm family Arecaceae, native to the Canary Islands off the coast of Morocco. It is a relative of ''Phoenix dactylifera'', the true dat ...'') and many green spaces. Both the park and the former casino were named National Monuments on February 25, 1988, and the majority of the houses situated in the park are private homes. It has become an attractive walking destination, following its restoration. The Park was severely damaged after the 2010 Pichilemu earthquake, with all of the balustrades surrounding the park being destroyed. References National Monuments of Chile in Pichilemu Building ...

Cardenal Caro Province
Cardenal Caro Province ( es, Provincia Cardenal Caro) is one of the three provinces of the central Chilean region of O'Higgins (VI). The capital of Cardenal Caro is Pichilemu. Name The province is named after Cardinal José María Caro Rodríguez, native of Pichilemu, and who was the first Cardinal of Chile. History On July 13, 1973, President Salvador Allende Gossens decreed the creation of the Cardenal Caro Department. The decree was published in the Diario Oficial de la República de Chile in August of the same year, making it official. Marchigüe was declared the capital. However, the coup d'état that occurred in September of that year made the decree "dead text". The province of Cardenal Caro was created on October 3, 1979 by General Augusto Pinochet. The communes of Litueche (formerly El Rosario), La Estrella, Marchihue, Paredones, and Pichilemu, originally from Colchagua Province; and Navidad, originally from San Antonio Province, formed the province.
