Earthquakes In Chile
__NOTOC__ Chile lay in a region which is adjacent to the fast-moving Nazca Plate, and has high tectonic activity. The records for earlier centuries are apparently incomplete. Of the world's 46 known earthquakes with M ≥ 8.5 since the year 1500, one-third occurred in Chile and are shown in the map to the side. Some virtually have the same epicenters like the 1604 and 1868 (in Arica), the 1730 and 1822 (in Valparaíso), the 1751 and 1835 (in Concepción), and the 1575 and 1837 (in Valdivia). The strongest known recorded in modern times was also in Chile, the 1960 Valdivia earthquake.

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] |
El Mercurio
''El Mercurio'' (known online as ''El Mercurio On-Line'', ''EMOL'') is a Chilean newspaper with editions in Valparaíso and Santiago. Its Santiago edition is considered the country's newspaper of record and it is considered the oldest daily in the Spanish language currently in circulation. ''El Mercurio'' is owned by El Mercurio S.A.P. (''Sociedad Anónima Periodística'' 'joint stock news company'), which operates a network of 19 regional dailies and 32 radio stations across the country. History The Valparaíso edition of ''El Mercurio'' was founded by Pedro Félix Vicuña ( Benjamín Vicuña Mackenna's father) on September 12, 1827, and was later acquired by Agustín Edwards Ross in 1880. The Santiago edition was founded by Agustín Edwards Mac Clure, son of Edwards Ross, on June 1, 1900. In 1942 Edwards Mac Clure died and his son Agustín Edwards Budge took over as president. When Edwards Budge died in 1956, his son, Agustín Edwards Eastman, took control of the company. Edwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1950 Calama Earthquake
The 1950 Calama earthquake occurred near the Argentina–Chile border with an epicenter near Calama, Chile in the Atacama Desert on December 9. The event had a hypocenter depth of 113.9 km, beneath the Caichinque volcanic complex. It measured magitude 8.2 on the moment magnitude scale, making it the largest intermediate depth earthquake ever recorded on Chilean soil. One person was killed and an unspecified number of people were injured in Calama. Tectonic setting Earthquakes are frequent in Chile as it lies in the so-called Pacific Ring of Fire, where many of the world's active volcanoes and seismic activities are concentrated at. Off the coast of Chile, the Nazca Plate subducts beneath the South American Plate along the Peru–Chile or Atacama Megathrust, producing large earthquakes including the 1960 Chilean earthquake which had a magnitude of 9.5–9.6 on the moment magnitude scale. In some cases, intraslab earthquakes occur. These earthquakes do not occur on the subduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1949 Tierra Del Fuego Earthquake
The 1949 Tierra del Fuego earthquakes occurred slightly more than eight hours apart on 17 December. Their epicenters were located in the east of the Chilean Tierra del Fuego Province, close to the Argentine border on the island of Tierra del Fuego. The two shocks measured 7.7 and 7.6 on the moment magnitude scale and were the most powerful ever recorded in the south of Argentina and one of the most powerful in austral Chile. They were felt with intensities as high as VIII (''Severe'') on the Mercalli intensity scale, and affected the settlements of Punta Arenas and Río Gallegos.

1943 Ovalle Earthquake
The Coquimbo Region of Chile was affected by a major earthquake on 6 April 1943 at 12:07 local time (16:07 UTC). It had a magnitude of between 7.9 and 8.2 on the moment magnitude scale. It triggered a minor tsunami that caused local damage along the coast. A total of 11 people were killed, including a group of five miners. Tectonic setting Central Chile lies above the destructive plate boundary where the Nazca Plate subducts beneath the South American Plate. There have been many large earthquakes caused by rupture along the plate interface. Illapel has been struck by major earthquakes in 1730, 1880, 1943 and 2015.

1939 Chillán Earthquake
The 1939 Chillán earthquake occurred in south-central Chile on 24 January with a surface wave magnitude of 8.3 and a maximum Mercalli intensity of X (''Extreme''). With a death toll of around 28,000, compared to the 2,231–6,000 (official estimates vary greatly) (Exact data location missing from URL) of the Great Chilean earthquake of 1960, it is the single deadliest earthquake in Chile. Earthquake At 23:32, the earth began to shake strongly underneath Chillán, destroying more than half of it, including around 3,500 homes and the recently constructed Casa Rabié which then was in the city. Aftershocks followed although they were less intense, which left the city completely destroyed. Until then, the Cathedral of Chillán had been one of the principal buildings of the area, but it was completely destroyed. The church that was built to replace it was designed specifically to withstand future earthquakes. At 23:35, Concepción was violently hit. Almost all of the buildings (aro ...

1928 Talca Earthquake
The 1928 Talca earthquake occurred on 1 December at near Curepto, Maule Region, Chile, with an estimated magnitude of 7.6 MW, 8.3 MS and 7.9 ML. In Talca, it lasted 1 minute 45 seconds. There was damage between Valparaíso and Concepción, and severe damage on the coast from Cauquenes to Pichilemu, and in the following cities in the Chilean Central Valley: Talca, Curicó and San Fernando. In Talca there were 108 dead, 67 in Constitución, and 50 in the surrounding villages. Soon after the earthquake, the Barahona dam, in the valley of Cachapoal River, that contained copper tailings, collapsed, killing 54 miners. In total, there were 279 dead, 1,083 wounded and 127,043 homeless.

1906 Valparaíso Earthquake
The 1906 Valparaíso earthquake hit Valparaíso, Chile, on August 16 at 19:55 local time. Its epicenter was offshore from the Valparaíso Region, and its intensity was estimated at magnitude 8.2 . This earthquake occurred thirty minutes after the 1906 Aleutian Islands earthquake. Much of Valparaíso was destroyed; there was severe damage in central Chile from Illapel to Talca. The earthquake was felt from Tacna to Puerto Montt. Reports said the earthquake lasted four minutes. A tsunami was also generated. The earthquake killed a reported 3,882 people. The record of previous seismic activity includes major earthquakes in 1647, 1730 and 1822. The 1906 disaster was predicted by Captain Arturo Middleton, Chief of the Chilean Army Meteorological Office, in a letter that was published in ''El Mercurio'', one week before it occurred. Admiral Luis Gómez Carreño ordered the shooting of at least 15 people, who were caught looting after the earthquake. A Board for Reconstruction was fo ...

1822 Valparaíso Earthquake
The 1822 Valparaíso earthquake was a major earthquake that occurred in Valparaíso, Chile on November 19, 1822. The earthquake has an estimated surface wave magnitude of 8.5. It triggered a moderate tsunami measuring up to 12 feet or 3.6 meters along the Chilean coast. The earthquake and tsunami killed 72 to as much as 300 people and left a further 200 injured. Earthquake Based on the historical accounts from Maria Graham, a British travel writer who documented her experience in the earthquake, seismologists concluded that the event was likely a result of thrust faulting. A deep section of the Peru-Chile subduction zone ruptured at a plausible depth of around 40 km. This depth is similar to the 2007 Tocopilla and 1906 Valparaíso earthquakes. Damage The earthquake was felt for as much as five minutes. In Concón, three distinct jolts were felt with the second being the most intense and lasting two minutes. A loud rumbling noise that seemed to be emanating from the ground w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1819 Copiapó Earthquake
During April 1819, the area around Copiapó in northern Chile was struck by a sequence of earthquakes over a period of several days. The largest of these earthquakes occurred on 11 April at about 15:00 local time, with an estimated magnitude of 8.5. The other two events, on 3 April between 08:00 and 09:00 local time and on 4 April at 16:00 local time, are interpreted as foreshocks to the mainshock on 11 April. The mainshock triggered a tsunami that affected 800 km of coastline and was also recorded at Hawaii. The city of Copiapó was devastated. Tectonic setting Northern Chile lies above the destructive plate boundary where the Nazca Plate is being subducted beneath the South American Plate along the line of Peru–Chile Trench at about 8 cm per year. This part of the boundary is associated with many large megathrust earthquakes, including those in 1420 and 1922. Earthquake sequence The magnitudes of the two foreshocks is not known. The magnitude of the mainshock has been esti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1737 Valdivia Earthquake
The 1737 Valdivia earthquake struck south-central Chile on December 24 with an estimated moment magnitude of 7.5. Together with earthquakes in 1575 and 1837 the earthquake is among the historical predecessors to the great 1960 earthquake. While the overlap in affected areas is significant relative to the 1837 earthquake the 1737 earthquake may have occurred slightly more to the north. The earthquake was felt in Concepción but most damage occurred in the towns of Valdivia and Castro, Chiloé Archipelago. In both of these locations churches were destroyed by the earthquake. In addition the Valdivian Fort System and the Royal Storehouse of Valdivia took heavy damage. Landslides occurred next to Villarrica, Calafquén, and Riñihue lakes. Over all this indicates the rupture zone was about 640 km long, with most damage being concentrated in the middle section (Valdivia). There is no evidence the earthquake would have produced a tsunami. See also *Huilliche uprising of 1712 *Map ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
