The 1960 Valdivia earthquake (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) on 22 May 1960 is the most powerful earthquake ever recorded. Various studies have placed it at 9.4–9.6 on the moment magnitude scale. It occurred in the afternoon (19:11 GMT, 15:11 local time), and lasted approximately 10 minutes. The resulting tsunamis affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands.
The epicenter of this megathrust earthquake was near Lumaco, approximately 570 kilometres (350 mi) south of Santiago, with Valdivia being the most affected city. The tremor caused localised tsunamis that severely battered the Chilean coast, with waves up to 25 metres (82 ft). The main tsunami traveled across the Pacific Ocean and devastated Hilo, Hawaii. Waves as high as 10.7 metres (35 ft) were recorded 10,000 kilometres (6,200 mi) from the epicenter, and as far away as Japan and the Philippines.
The death toll and monetary losses arising from this widespread disaster are not certain. US$400 million to $800 million (or $3.46 billion to $6.91 billion today, adjusted for inflation).Various estimates of the total number of fatalities from the earthquake and tsunamis have been published, ranging between 1,000 and 7,000 killed. Different sources have estimated the monetary cost ranged from
The 1960 Chilean earthquakes were a sequence of strong earthquakes that affected Chile between 21 May and 6 June 1960, centered in the Araucanía, Aysén, and Bío Bío regions of the country. The first three quakes, all registering in the planet's top 10 by magnitude for 1960, are grouped together as the 1960 Concepción earthquakes. The first of these was the 8.1 Mw Concepción earthquake at 06:02 UTC-4 on 21 May 1960. Its epicenter was near Curanilahue. Telecommunications to southern Chile were cut off and President Jorge Alessandri cancelled the traditional ceremony of the Battle of Iquique memorial holiday to oversee the emergency assistance efforts. The second and third Concepción earthquakes occurred the next day at 06:32 UTC-4 (7.1 Mw) and 14:55 UTC-4 (7.8 Mw) on 22 May. These earthquakes formed a southward migrating foreshock sequence to the main Valdivia shock, which occurred just 15 minutes after the third event.
The earthquake interrupted and effectively ended Lota's coal miners' march on Concepción as they demanded higher salaries.
The Valdivia earthquake occurred at 15:11 UTC-4 on 22 May, and affected all of Chile between Talca and Chiloé Island, more than 400,000 square kilometres (150,000 sq mi). Coastal villages, such as Toltén, were struck. At Corral, the main port of Valdivia, the water level rose 4 m (13 ft) before it began to recede. At 16:20 UTC-4, a wave of 8 m (26 ft) struck the Chilean coast, mainly between Concepción and Chiloé. Another wave measuring 10 m (33 ft) was reported ten minutes later.
Hundreds of people were already reported dead by the time the tsunami struck. One ship, Canelos, starting at the mouth of the Valdivia River, sank after being moved 1.5 km (0.93 mi) backward and forward in the river; as of 2005, its mast was still visible from the road to Niebla.
A number of Spanish-colonial fortifications were completely destroyed. Soil subsidence also destroyed buildings, deepened local rivers, and created wetlands in such places as the Río Cruces and Chorocomayo, a new aquatic park north of the city. Extensive areas of the city were flooded. The electricity and water systems of Valdivia were totally destroyed. Witnesses reported underground water flowing up through the soil. Despite the heavy rains of 21 May, the city was without a water supply. The river turned brown with sediment from landslides and was full of floating debris, including entire houses. The lack of potable water became a serious problem in one of Chile's rainiest regions.[ citation needed ]
The earthquake did not strike all the territory with the same strength; measured with the Mercalli scale, tectonically depressed areas suffered heavier damage. The two most affected areas were Valdivia and Puerto Octay, near the northwest corner of Llanquihue Lake. Puerto Octay was the center of a north–south elliptical area in the Central Valley, where the intensity was at the highest outside the Valdivia Basin.East of Puerto Octay, in a hotel in Todos los Santos Lake, stacked plates were reported to have remained in place. Excepting poor building sites, the zone of Mercalli scales intensities of VII or more all lay west of the Andes in a strip running from Lota (37° S) southwards. The area of intensities of VII or more did not penetrate into the Central Valley north of Lleulleu Lake (38° S) and south of Castro (42.5° S).
Two days after the earthquake Cordón Caulle, a volcanic vent close to Puyehue volcano, erupted. Other volcanoes may also have erupted, but none were recorded because of the lack of communication in Chile at the time. The relatively low death toll in Chile (5,700) is explained in part by the low population density in the region, and by building practices that took into account the area's high geological activity.
One of the main aftershocks occurred on 6 June in Aysén Region.This earthquake probably occurred along the Liquiñe-Ofqui Fault, meaning in this case that the fault would have moved as a consequence of the 22 May Valdivia earthquake.
The earthquake was a megathrust earthquake resulting from the release of mechanical stress between the subducting Nazca Plate and the South American Plate, on the Peru–Chile Trench. The focus was relatively shallow at 33 km (21 mi), considering that earthquakes in northern Chile and Argentina may reach depths of 70 km (43 mi).
Subduction zones are known to produce the strongest earthquakes on earth, as their particular structure allows more stress to build up before energy is released. Geophysicists consider it a matter of time before this earthquake will be surpassed in magnitude by another. The earthquake's rupture zone was 800 km (500 mi) long, stretching from Arauco (37° S) to Chiloé Archipelago (43° S). Rupture velocity, the speed at which a rupture front expands across the surface of the fault, has been estimated as 3.5 km (2.2 mi) per second. The average slip across all 27 Nazca subfaults was estimated to be 11 m, with 25–30 m of slip 200–500 km south of the epicenter on offshore subfaults.
While the Valdivia earthquake was extraordinarily large, the 2016 Chiloé earthquake hints that it did not unleash all available slip in the area.
Earthquake-induced tsunamis affected southern Chile, Hawaii, Japan, the Philippines, China, 25 m (82 ft). The main tsunami crossed the Pacific Ocean at a speed of several hundred km/h and devastated Hilo, Hawaii, killing 61 people. Most of the tsunami-related deaths in Japan occurred in the northeast Sanriku region of Honshu.eastern New Zealand, southeast Australia, and the Aleutian Islands. Some localized tsunamis severely battered the Chilean coast, with waves up to
The Chilean coast was devastated by a tsunami from Mocha Island (38° S) to Aysén Region (45° S). Across southern Chile, the tsunami caused huge loss of life, damage to port infrastructure, and the loss of many small boats. Further north, the port of Talcahuano did not suffer any major damage, only some flooding. Some tugboats and small sailboats were stranded on Rocuant Island near Talcahuano.
After the 21 May Concepción earthquake, people in Ancud sought refuge in boats. A carabinero (police) boat, Gloria, was towing a few of these boats when the second earthquake struck on 22 May. As the sea regressed Gloria became stranded between Cerro Guaiguén and Cochinos Island. The stranded boat was wrecked when a tsunami wave engulfed it.
All the new infrastructure of the small port of Bahía Mansa was destroyed by the tsunami, that reached heights of up to 10 metres above sea level there. The boat Isabella in Bahía Mansa quickly left the port but lost its anchors.
In the Valdivia River and Corral Bay, several vessels were wrecked by the earthquake, among them Argentina, Canelos, Carlos Haverbeck, Melita, and the salvaged remnants of Penco. Canelos was anchored at Corral when the quake struck, filling a cargo of wood and other products destined for northern Chile. The engine of Canelos was warmed up after the earthquake. After hours of drifting around in Corral Bay and Valdivia River, the ship was wrecked and subsequently abandoned by its crew at 18.00 PM. Two men on board Canelos died in the incident. As of 2000, the remnants of Canelos were still visible.
Santiago, another ship anchored at Corral at the time of the quake, managed to leave Corral in a bad state but was wrecked off the coast of Mocha Island on 24 May.The schooner La Milagrosa departed from Queule on 22 May to load a cargo of Fitzroya wood shingles in a small port south of Corral. La Milagrosa was battered by the currents and waves of the tsunami for four days while moving south. Outside Corral the crew rescued six nearly unconscious and dehydrated children on board two boats. The boats found were used to navigate in Valdivia River and Corral Bay but had drifted into the high sea.
At the coastal town of Queule, a carabinero reported hundreds of people dead or missing some days after the tsunami. Historians Yoselin Jaramillo and Ismael Basso report that people in Queule decades later know about 50 people to have died because of the earthquake and tsunami.
The earthquake triggered numerous landslides, mainly in the steep glacial valleys of the southern Andes. Within the Andes, most landslides occurred on forested mountain slopes around the Liquiñe-Ofqui Fault. Some of these areas remain sparsely vegetated while others have naturally developed more or less pure stands of Nothofagus dombeyi .These landslides did not cause many fatalities nor significant economic losses because most of the areas were uninhabited, with only minor roads.
One landslide caused destruction and alarm following its blockage of the outflow of Riñihue Lake (see "Riñihuazo" section below). About 100 km (62 mi) south of Riñihue Lake, landslides in the mountains around Golgol River caused the river to dam up; when it burst through the earthen dam, it created a flood down to Puyehue Lake. The Golgol landslides destroyed parts of international Route 215-CH, which connects to Bariloche in Argentina through Cardenal Antonio Samoré Pass.
While most landslides clustered around north–south strips in the Andes, other areas that were affected by a large numbers of earthquakes were the coast, mainly the foot of the Chilean Coast Range, and the shores of Llanquihue Lake.
A seiche of more than 1 meter was observed on Panguipulli Lake following the earthquake. km away from Valdivia. The wave, most likely produced by an earthquake-triggered sediment slide at the lake bottom, killed two people and destroyed a pier in San Carlos de Bariloche city.On 22 May, a seiche occurred also in Nahuel Huapi Lake, on the Argentinean side of the Andes, more than 200
During the Great Chilean earthquake, several landslides west of Tralcán Mountain blocked the outflow of Riñihue Lake. Riñihue Lake is the lowest of the Seven Lakes chain and receives a constant inflow from the Enco River.The blocked San Pedro River, which drains the lake, passes through several towns before reaching the city of Valdivia near the coast.
As the San Pedro River was blocked, the water level of Riñihue Lake started to rise quickly. Each meter the water level rose was equivalent to 20 million cubic meters, which meant that 480 million cubic meters of water would release into the San Pedro River (easily overpowering its flow capacity of 400 cubic metres (14,000 cu ft) per second if it rose above the final, 24-meter-high dam. This potential disaster would have violently flooded all the settlements along the course of the river in less than five hours, with more dire consequences if the dam suddenly broke.
About 100,000 people lived in the affected zone.Plans were made to evacuate Valdivia, and many people left. To avoid the destruction of the city, several military units and hundreds of workers from ENDESA, CORFO, and MOP started an effort to control the lake. Twenty-seven bulldozers were put into service, but they had severe difficulties moving in the mud near the dams, so dykes had to be constructed with shovels from June onwards. The work was not restricted to the lake; drainages from other parts of the Seven Lakes were dammed to minimize additional flow into Riñihue Lake. These dams were removed later, with the exception of Calafquén Lake, which still retains its dam.
By 23 June, the main dam had been lowered from 24 to 15 m (79 to 49 ft), allowing 3 billion cubic metres of water to leave the lake gradually, but still with considerable destructive power. The team was led by ENDESA engineer Raúl Sáez.
On 24 May, 38 hours after the main shock of the 1960 Valdivia earthquake, the Cordón Caulle volcano erupted.The eruption was believed to have been triggered by the earthquake. Between two sparsely populated and isolated Andean valleys, the eruption had few eyewitnesses and received little attention by local media, which was preoccupied with the severe and widespread damage and losses caused by the earthquake. The eruption was first noticed and reported as an explosion by the crew of a United States Air Force plane that was heading to Santiago from Puerto Montt.
The eruption fed a 5.5 km long fissure on 135° heading where 21 individual vents have been found. These vents produced an output of about 0.25 km3 DRE both in form of lava flows and tephra. The eruption ended on 22 July, 59 days later.
As a result of an evacuation plan, there were no reported human deaths associated with the eruption.
The levels of material damage were relatively low given the high magnitude of the earthquake. Part of the reason behind this was the limited infrastructure development of the region next to the rupture zone.Structures that had been designed to resist earthquakes performed well during the earthquake, chiefly suffering damage when affected by soil subsidence or small fault movements. Houses built by their owners fared badly. In the regions of Maule and Bío Bío, houses built from adobe and masonry proved weak, while from Araucanía to the south weak houses were mainly those built with inappropriate wood that had decayed over time.
It has been estimated that about 40 percent of the houses in Valdivia were destroyed, leaving 20,000 people homeless.The most affected structures were those built of concrete, which in some cases collapsed completely, because they were not built using modern earthquake engineering. Traditional wooden houses fared better; although many were uninhabitable if they did not collapse. Houses built upon elevated areas suffered considerably less damage compared to those on the lowlands, which absorbed great amounts of energy. Many city blocks with destroyed buildings in the city center remained empty until the 1990s and 2000s, with some of them still used as parking lots. Before the earthquake, some of these blocks had modern concrete buildings built after the Great Valdivia fire of 1909.
Valdivia's bridges suffered only minor damage. Land subsidence in Corral Bay improved navigability as shoal banks, produced earlier by sediments from Madre de Dios and other nearby gold mines, sank and were compacted.As the earthquake destroyed Valdivia's flood barriers, general land subsidence exposed new areas to flooding.
The United States quickly set up a field hospital following the earthquake.Aided by the United States, a geological survey of Valdivia was done following the earthquake and resulted in the city's first geological map. Mexico built and donated the public school Escuela México after the earthquake.
The earthquakes damaged an area that had suffered a long period of economic decline, which began with shifts in trade routes due to the expansion of railroads in southern Chile and the opening of the Panama Canal in 1914.
Unlike Valdivia, Osorno was saved from major destruction. In Osorno only about 20 houses were totally destroyed, although many firewalls and chimneys collapsed.
Puerto Montt, a major city today, had in the early 1960s about 49,500 inhabitants. The bulk of the damage in Puerto Montt was located in the neighborhood of Barrio Modelo and the northern part of Bahía Angelmó, where artificial fills subsided.Angelmó and other coastal areas of Puerto Montt were among the few urban areas that suffered "total destruction" by the earthquake.
The tsunami that struck the coast of southern Chile destroyed seaside farms, killing numerous livestock and people.Barns and industrial structures were destroyed by the quake. The dairy industry was among the few industries of the affected zone that received subsidies and investment after the earthquake. It received state support through a long-term policy after the earthquake.
As a result of the earthquake, an international technological cooperation programme was established in the dairy sector. More specifically, the German and Danish governments helped to create the Centro Tecnológico de la Leche (the Milk Technological Centre) in the Southern University of Chile.The scholar Erik Dahmén believes that the earthquake resulted in a "creative destruction" for farmers of Southern Chile.
The economy of the coastal town of Queule had during the 1950s developed significantly. Its economy based on fishing, agriculture and industry had grown. Queule was connected by road in 1957 to the rest of the country and the town had developed into a balneario. This era of prosperity ended with the 1960 earthquake.
Further north the earthquake destroyed numerous houses in the coal-mining town of Lebu.
After the 1960 Valdivia earthquake, a committee was formed to solve problems caused by the earthquake. It continued to operate, to develop approaches for national emergencies.[ citation needed ] In 1974, after the 1971 eruption of Villarrica volcano, the committee was officially founded as ONEMI (Spanish acronym for Ministry of Interior National Emergency Office) when it was authorized by law as an independent governmental office.
In the coastal village Collileufu (La Araucanía Region), native Lafkenches carried out a ritual human sacrifice during the days following the main earthquake. Collileufu, located in the Budi Lake area, south of Puerto Saavedra, was in 1960 highly isolated. The Mapuche spoke primarily Mapudungun. The community had gathered in Cerro La Mesa, while the lowlands were struck by successive tsunamis. Juana Namuncura Añen, a local machi, demanded the sacrifice of the grandson of Juan Painecur, a neighbor, in order to calm the earth and the ocean.The victim was 5-year-old José Luis Painecur, an "orphan" (huacho) whose mother had gone to work as a domestic worker in Santiago and left her son under the care of her father.
The sacrifice was learned about by authorities after a boy in the commune of Nueva Imperial denounced to local leaders the theft of two horses; these were allegedly eaten during the sacrifice ritual.Two men were charged with the crime of murder and confessed, but later recanted. They were released from prison after two years. A judge ruled that those involved had "acted without free will, driven by an irresistible natural force of ancestral tradition". The story was mentioned in a Time magazine article, although with little detail.
There is evidence that a similar earthquake and landslide occurred in 1575 in Valdivia.This earthquake was of similar strength and also caused a Riñihuazo. According to the chronicle of Mariño de Lobera, corregidor of Valdivia in 1575, a landslide blocked the outflow of the lagoon of Renigua. Several months later in April, it caused a flood. He said that the Spanish settlers had evacuated and waited on high ground until after the dam burst, but many aboriginals died in the flood waters. While the 1575 earthquake is considered the one most similar to that of 1960, it differed in not having caused any tsunami in Japan.
Other lesser earthquakes that preceded the 1960 event occurred in 1737 and 1837.
On 27 February 2010 at 03:34 local time, an 8.8 magnitude earthquake occurred just to the north (off the coast of the Maule region of Chile, between Concepción and Santiago). 35 kilometres (22 mi) deep and several miles off shore. This 2010 Chile earthquake may be related or consequential to the 1960 tremor.This quake was reported to be centered approximately
Villarrica is one of Chile's most active volcanoes, rising above the lake and town of the same name, 750 km (470 mi) south of Santiago. It is also known as Rucapillán, a Mapuche word meaning "devil's house". It is the westernmost of three large stratovolcanoes that trend NW-SW obliquely perpendicular to the Andean chain along the Mocha-Villarrica Fault Zone, along with Quetrupillán and the Chilean portion of Lanín, are protected within Villarrica National Park. Guided ascents are popular during summer months.
The Los Ríos Region is one of Chile's 16 regions, the country's first-order administrative divisions. Its capital is Valdivia. It began to operate as a region on October 2, 2007, having been created by subdividing the Los Lagos Region in southern Chile. It consists of two provinces: Valdivia and the newly created Ranco Province, which was formerly part of Valdivia Province.
Valdivia is a city and commune in southern Chile, administered by the Municipality of Valdivia. The city is named after its founder Pedro de Valdivia and is located at the confluence of the Calle-Calle, Valdivia, and Cau-Cau Rivers, approximately 15 km (9 mi) east of the coastal towns of Corral and Niebla. Since October 2007, Valdivia has been the capital of Los Ríos Region and is also the capital of Valdivia Province. The national census of 2002 recorded the commune of Valdivia as having 140,559 inhabitants (Valdivianos), of whom 127,750 were living in the city. The main economic activities of Valdivia include tourism, wood pulp manufacturing, forestry, metallurgy, and beer production. The city is also the home of the Austral University of Chile, founded in 1954 and the Centro de Estudios Científicos.
The Llaima Volcano is one of the largest and most active volcanoes in Chile. It is situated 82 km northeast of Temuco and 663 km southeast of Santiago, within the borders of Conguillío National Park.
Mocho-Choshuenco is a glacier covered compound stratovolcano in the Andes of Los Ríos Region, Chile. It is made of the twin volcanoes Choshuenco in the northwest and the Mocho in the southeast. The highest parts of the volcano are part of the Mocho-Choshuenco National Reserve while the eastern slopes are partly inside the Huilo-Huilo Natural Reserve.
Tralcán is a triangular-shaped mountain, which is located near Riñihue Lake, Chile. It is located south of the outflow dividing western Riñihue in two arms. Despite having been sacred to the huilliches for centuries, the mount became famous when several landslides near Tralcan dammed the Riñihue Lake after the 1960 Valdivia earthquake. The water levels in the lake rose more than 20 m and became a threat to the existence of Valdivia city. These events came to be known as The Riñihuazo. There is evidence that a similar landslide occurred after the 1575 Valdivia earthquake.
The Riñihue Lake is a lake of glacial origin in eastern Valdivia Province, southern Chile. It is surrounded by several mountains. The eastern side receives the waters of the Panguipulli Lake by the Enco River, its main contributor. It is the last of the Seven Lakes chain. In the west it is cut into two arms by the Tralcán Mount, and on the east side lies the Mocho-Choshuenco volcano. In the south the lake is bounded by the Cerros de Quimán mountains.
The Riñihuazo is the name given to the landslide damming of Riñihue Lake on 22 May 1960, after a landslide caused by the Great Chilean earthquake blocked its outflow. According to the chronicler Mariño de Lobera a similar event occurred after the 1575 Valdivia earthquake.
San Pedro River is a river in Valdivia Province, southern Chile. It drains waters from the Riñihue Lake, the last of the Seven Lakes, to the Calle-Calle River, which in turn changes name to Valdivia River and at the end outflows in Corral Bay. San Pedro River is well known for being a good fishing area and a good place to practise rafting.
The geology of Chile is a characterized by processes linked to subduction such as volcanism, earthquakes and orogeny. The buildings blocks of Chile's geology assembled during the Paleozoic Era. Chile was by then the southwestern margin of the supercontinent Gondwana. In the Jurassic Gondwana begun to split and the ongoing period of crustal deformation and mountain building known as the Andean orogeny begun. In the Late Cenozoic Chile definitely separated from Antarctica, the Andes expienced a great rise accomplained by a cooling climate and the onset of glaciations.
A landslide dam or barrier lake is a natural damming of a river by some kind of landslides, such as debris flows and rock avalanches, or by volcanic eruptions. If the damming landslides are caused by an earthquake, it may also be called a quake lake. Some landslide dams are as high as the largest existing artificial dam.
The 1575 Valdivia earthquake occurred at 14:30 local time on December 16. It had an estimated magnitude of 8.5 on the surface wave magnitude scale and led to the flood of Valdivia, Chile.
Valdivia is one of the few cities in southern Chile with a more less continuous and well documented history from its foundation in the 16th century onwards.
The 2010 Chile earthquake occurred off the coast of central Chile on Saturday, 27 February at 03:34 local time, having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes. It was felt strongly in six Chilean regions, that together make up about 80 percent of the country's population. According to the United States Geological Survey (USGS) the cities experiencing the strongest shaking—VIII (Severe) on the Mercalli intensity scale (MM)—were Concepción, Arauco and Coronel. According to Chile's Seismological Service Concepción experienced the strongest shaking at MM IX (Violent). The earthquake was felt in the capital Santiago at MM VII or MM VIII. Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru.
The maritime history of Chile begins with the independence of Chile, but traces it origin in the colonial era and has ultimately origin in the seafaring tradition of the Iberian Peninsula, Europe and the Mediterranean as well as from indigenous peoples of Chile.
The 1985 Rapel Lake earthquake occurred on 8 April at 21:56:59 local time with a moment magnitude of 7.5 and a maximum perceived intensity of VII. The shock was centered 75 kilometres (47 mi) southwest of Santiago, Chile, with a focal depth of 37.8 km (23 mi).
The 2010 Pichilemu earthquake, also known as the Libertador O'Higgins earthquake, was a 6.9 MW intraplate earthquake that struck Chile's O'Higgins Region on 11 March 2010. The earthquake was centred 15 kilometres (9.3 mi) northwest of the city of Pichilemu.
The 1837 Valdivia earthquake struck south-central Chile on November 17. Together with earthquakes in 1575 and 1737 the earthquake is among the historical predecessors to the great 1960 earthquake. The rupture zone was roughly from Valdivia to the south. It was felt in the cities of Concepción, Valdivia and Ancud. The earthquake was also felt by the crew whaling ships in Guafo Island and Chonos Archipelago. Various landslides were triggered in Chiloé and people are reported to have been thrown to the ground in Valdivia. In contrast in Concepción the shakings were moderate. As reported in various coastal localities the ground rose as result of the earthquake. Decades later while surveying southern Chile’s coasts Francisco Vidal Gormaz was told of islands that been submerged and some that had emerged as a consequence of the earthquake. The earthquake caused a tsunami that struck Hawaii, what is now French Polynesia and Japan.
The 1737 Valdivia earthquake struck south-central Chile on December 24. 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.
