Concepción is a city and commune in central Chile, and the geographical and demographic core of the Greater Concepción metropolitan area, one of the three major conurbations in the country. It has a significant impact on domestic trade being part of the most heavily industrialized region in the country. It is the seat of the Concepción Province and the capital of the Bío Bío Region. It sits about 500 km south of the nation's capital, Santiago.
The 1960 Valdivia earthquake and tsunami or the Great Chilean earthquake on 22 May 1960 was 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, and lasted for approximately 10 minutes. The resulting tsunamis affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands.
The Arauco War was a long-running conflict between colonial Spaniards and the Mapuche people, mostly fought in the Araucanía. The conflict began at first as a reaction to the Spanish conquerors attempting to establish cities and force Mapuches into servitude. It subsequently evolved over time into phases comprising drawn-out sieges, slave-hunting expeditions, pillaging raids, punitive expeditions, and renewed Spanish attempts to secure lost territories. Abduction of women and war rape was common on both sides.
The Destruction of the Seven Cities is a term used in Chilean historiography to refer to the destruction or abandonment of seven major Spanish outposts in southern Chile around 1600, caused by the Mapuche and Huilliche uprising of 1598. The Destruction of the Seven Cities, in traditional historiography, marks the end of the Conquest period and the beginning of the proper colonial period.
The Conquest of Chile is a period in Chilean historiography that starts with the arrival of Pedro de Valdivia to Chile in 1541 and ends with the death of Martín García Óñez de Loyola in the Battle of Curalaba in 1598, and the destruction of the Seven Cities in 1598–1604 in the Araucanía region.
Francisco Vidal Gormaz was a Chilean naval officer and hydrographer who explored the coasts of Chile including some river systems and lakes. During the 1850s he explored and surveyed several times Maullín River with Francisco Hudson. Before being lost at sea in 1859 Hudson is thought to have been a major influence on Vidal Gormaz. He participated in the Occupation of the Araucanía performing reconnaissance missions in the coasts of Arauco and Toltén. In 1863, he was named director of the Maritime School of Ancud. In 1874, he became the first director of the newly created Hydrographic Office. In 1884, he became General Inspector of Lighthouses and participated in the International Meridian Conference. Because of his neutrality during the 1891 Chilean Civil War he was removed from his post as director of the Hydrographic Office. He was named assistant at the Sea Ministry in 1894 and retired from the navy in 1899.
The 1995 Antofagasta earthquake occurred on July 30 at 05:11 UTC with a moment magnitude of 8.0 and a maximum Mercalli intensity of VII. The Antofagasta Region in Chile was affected by a moderate tsunami, with three people killed, 58 or 59 injured, and around 600 homeless. Total damage from the earthquake and tsunami amounted to $1.791 million.
The 2010 Chile earthquake and tsunami 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 1835 Concepción earthquake occurred near the neighboring cities of Concepción and Talcahuano in Chile on 20 February at 11:30 local time and has an estimated magnitude of about 8.5 . The earthquake triggered a tsunami which caused the destruction of Talcahuano. A total of at least 50 people died from the effects of the earthquake and the tsunami. The earthquake caused damage from San Fernando in the north to Osorno in the south. It was felt over a still wider area from Copiapó in the north to the island of Chiloe in the south and as far west as the Juan Fernández Islands.
The Sanriku Coast is a coastal region on the Pacific Ocean, extending from southern Aomori Prefecture, through Iwate Prefecture and northern Miyagi Prefecture in northeastern Honshū, which is Japan's main island. The name comes from the historical region of Sanriku, referring to the former provinces of Rikuō, Rikuchū and Rikuzen.
The 1960 Concepción earthquakes were a succession of three destructive earthquakes that happened between 21 and 22 May 1960. They formed part of the foreshock sequence for the 1960 Valdivia earthquake, the largest recorded earthquake in history.
The 1615 Arica earthquake was a major earthquake centered near Arica in the Spanish colonial Viceroyalty of Peru, within the present day Arica y Parinacota Region of northwestern Chile.
As an archaeological culture, the Mapuche people of southern Chile and Argentina have a long history which dates back to 600–500 BC. The Mapuche society underwent great transformations after Spanish contact in the mid–16th century. These changes included the adoption of Old World crops and animals and the onset of a rich Spanish–Mapuche trade in La Frontera and Valdivia. Despite these contacts Mapuche were never completely subjugated by the Spanish Empire. Between the 18th and 19th century Mapuche culture and people spread eastwards into the Pampas and the Patagonian plains. This vast new territory allowed Mapuche groups to control a substantial part of the salt and cattle trade in the Southern Cone.
The Dutch expedition to Valdivia was a naval expedition, commanded by Hendrik Brouwer, sent by the Dutch Republic in 1643 to establish a base of operations and a trading post on the southern coast of Chile. With Spain and the Dutch Republic at war, the Dutch wished to take over the ruins of the abandoned Spanish city of Valdivia. The expedition sacked the Spanish settlements of Carelmapu and Castro in the Chiloé Archipelago before sailing to Valdivia, having the initial support of the local natives. The Dutch arrived in Valdivia on 24 August 1643 and named the colony Brouwershaven after Brouwer, who had died several weeks earlier. The short-lived colony was abandoned on 28 October 1643. Nevertheless, the occupation caused great alarm among Spanish authorities. The Spanish resettled Valdivia and began the construction of an extensive network of fortifications in 1645 to prevent a similar intrusion. Although contemporaries considered the possibility of a new incursion, the expedition was the last one undertaken by the Dutch on the west coast of the Americas.
The 1837 Valdivia earthquake struck south-central Chile on November 7. 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 Mapuche uprising of 1655 was a series of coordinated Mapuche attacks against Spanish settlements and forts in colonial Chile. It was the worst military crisis in Chile in decades, and contemporaries even considered the possibility of a civil war among the Spanish. The uprising marks the beginning of a ten-year period of warfare between the Spanish and the Mapuche.
The 1604 Arica earthquake is an earthquake that occurred at 1:30 pm on November 24, 1604, offshore Arica, Chile. The estimated magnitude range is 8.0–8.5 and possibly up to 9.0 . It had a destructive tsunami that destroyed Arica and caused major damage at Arequipa. 1,200 km of coastline were affected by the tsunami. The recorded effects of this earthquake are very similar to those for the 1868 Arica event, suggesting a similar magnitude and rupture area of the megathrust between the subducting Nazca Plate and the overriding South American Plate. Tsunami deposits have been identified on the Chatham Islands that are likely to have been caused by a trans-Pacific tsunami caused by the 1604 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 ft (3.7 m) along the Chilean coast. The earthquake and tsunami killed between 72 and 300 people and left a further 200 injured.
The 1657 Concepción earthquake occurred on March 15 at 20:00 local time off the coast of Concepción, Biobío Region in the Spanish Empire. The earthquake caused severe damage along the coast, and generated a large tsunami in the Bay of Concepción. At least 40 people were killed, the majority due to drowning from the tsunami. The town of Concepción was the hardest hit, with the earthquake and tsunami totally destroying it.
