Antofagasta

The city of Antofagasta is closely linked to mining activity, being a port and the chief service hub for one of Chile's major mining areas. While silver and saltpeter mining have been historically important for Antofagasta, since the mid-19th century copper mining is by far the most important mining activity for Antofagasta, fueling a steady growth in the areas of construction, retail, hotel accommodations, population growth and skyline development until the end of the 2000s commodities boom in 2013. Since the 2010s Antofagasta is also a service hub for lithium mining. The seat of one of Chile's three environmental courts and is also a university city being the home of the Catholic University of the North and the University of Antofagasta. In 2012, Antofagasta has the highest GDP per capita of Chile, US$37,000 and the 3rd place for Human Development Index just after Metropolitana de Santiago Region and Magallanes and Antártica Chilena Region.

• Name — Antofagasta • Type — City and commune • Nickname — La perla del Norte ("Pearl of the North") • Motto — "Gloria, patria y tesón es tu lema y tu honor"

The name of Antofagasta is "presumably" derived from the name of Antofagasta de la Sierra in Catamarca Province, Argentina.

The territory was disputed between Chile and Bolivia until the signing of the Boundary Treaty of 1866. On 18 September 1866, José Santos Ossa and Francisco Puelma achieved the award of the concession of nitrate lands, following a request taken to the Bolivian government. The exploring of the Chilean miners found rich deposits of saltpeter (nitratine) in the field of Salar del Carmen, to the east of the present Antofagasta. Agreed to form the "Sociedad Exploradora del Desierto de Atacama" (Explorer Society of Atacama Desert). After the formation of the company, began to fill with what was called "La Chimba". On 8 May 1872, Antofagasta was designated by the Bolivian Government as Puerto Mayor, opening trade worldwide. On 27 November 1873, the "Compañía de Salitres y Ferrocarril de Antofagasta" (CSFA), a Chilean mining company, signed a contract with the government of Bolivia, in which taxes were removed from mineral exploitation for 15 years. This contract was not ratified by the Congress of Bolivia, which was then analyzed negotiations with Chile.

This would be used as an argument 5 years later in Chile, when it unleashed the War of the Pacific. The secret alliance forbade Bolivia from signing a border treaty with Chile, without consulting with Peru. However, in 1874 Chile and Bolivia signed a border treaty, which replaced the previous treaty of 1866. One of its points was not to impose new taxes on individuals, industries and Chilean capital for 25 years. For Bolivia, the contract of 1873 between the government and CSFA was not yet in force, because, according to the Bolivian constitution, all contracts with the Bolivian government had to be approved by the congress. According to the Bolivian version of events, the contract with the saltpeter company was incomplete so the congress, to approve the contract, decided to enforce a tax of 10 cents, which did not violate the treaty of 1874, since the contract was not yet in force at that date. Bolivia suspended the tax in deference to the government of Chile, but following a note from the Chilean foreign minister, it reactivated the tax law, then cancelled and closed the "Compañía de Salitres". Faced with a looming conflict with Chile, Bolivia decided to claim support under the agreement signed with Peru, and the treaty became effective with the Chilean occupation of Antofagasta, on 14 February 1879.

In 1912, the British community (La Colonia Britanica) erected a clock tower, replicating Big Ben, in Plaza Colón to celebrate the republic's centenary. • Illustration — Antofagasta in June 1941 In 1956, the Universidad del Norte (now the Catholic University of the North) was founded, due to support from the Catholic University of Valparaíso. On 9 October, of the same year began the negotiations for the creation of the "Centro Universitario Zona Norte" (University Center North Zone), part of the University of Chile. On 18 June 1991, a mudslide devastated much of the city, undermining land, damaged 2,464 houses and destroyed 493 buildings. Material damage was estimated at $70,000,000. The disaster left 92 dead, 16 missing and about 20,000 homeless. On 30 July 1995, the city was hit by an earthquake measuring 7.3 on the Richter Scale, with an intensity VII to VIII on the Mercalli Scale. • Illustration — View of the south of Antofagasta in 2005

• Illustration — Tropic of Capricorn Monument • Illustration — Natural Monument La Portada The city has an average elevation of 40 m. With an area of 30,718.1 30718.1 km2, it is the 3rd-largest commune in Chile. The urban area of Antofagasta begins abruptly, breaking the monotony of the desert and is located in the coastal plains, south of Mejillones Peninsula and north of "Cerro Coloso". The Tropic of Capricorn passes in the north of the city, outside the urban area, which is located the Cerro Moreno International Airport. The Tropic of Capricorn Monument was opened on 21 December 2000 in celebration of this. Designed by the architect Eleonora Roman, it was created to point the Tropic of Capricorn and to work as a Solar Calendar. Antofagasta was declared a partial common in the border area 20 July 1999, by Supreme Decree No. 1166 of the Ministry of Foreign Affairs. The city has little vegetation because it is situated in the Atacama Desert, which is the world's driest nonpolar desert. However, among the vegetated areas are a series of urban wetlands. Native reptiles, arthropods, birds like the Calidris and mammals like the culpeo fox, inhabit or visit the wetlands. Some of these wetlands are threatened by garbage, street dogs, extraction of water, establishments of shacks (ruco) and the diversion of water courses. As of January 2024 the municipality of Antofagasta plans to declare the wetlands official urban wetlands in accordance with the Urban Wetlands Law.

• Illustration — Average air temperatures in Antofagasta, 1951 to 2008, by (NASA) The town of Antofagasta has a cold desert climate (Köppen BWk) with abundant sunshine and strong maritime influence. The marked aridity and water scarcity are regulated by the Humboldt Current, in addition to the high humidity and morning fog known as "Camanchaca". Furthermore, the Pacific anticyclone generates winds from the south and southwest. The average annual temperature is 16.8 °C. The average daily low temperature in the warmest month, January, is 17.5 °C while the average daily high temperature is 23.2 °C. The coldest month, July, sees an average low temperature of 11.8 °C and an average high temperature of 16.5 °C. The highest temperature recorded is 30.0 °C in January 1998 and the lowest recorded is 3.0 °C in September 1978. The Atacama Desert coast is subject to a climate of extreme aridity, and therefore generates a low average annual rainfall of 3.4 mm (1970–2000), and the Town of Antofagasta itself receives an annual average of less than 0.1 mm of rainfall per year, earning it the record as the world's driest town. However, the sporadic occurrence of heavy rainfall, together with the geomorphologic situation of the city, make it susceptible to be affected by mud flows and landslides. Between 1916 and 1999, the city was affected by floods or landslides on seven occasions: 1925, 1930, twice in 1940, 1982, 1987 and 1991, of which the most important episodes in 1940 and 1991. • Illustration — Topographic relief around Antofagasta • Illustration — Cerro Coloso • Illustration — Cerro Moreno and Bahía Moreno

• Illustration — Quebrada El Carrizo There are about fifteen streams that have watersheds with accumulation of sand and gravel. Within the broader watershed (hoya) are the "Hoya La Chimba", "Hoya Caracoles", "Hoya La Cadena", "Hoya La Negra" and "Hoya El Way". These watersheds and their streams (Quebrada), such as "Quebrada sin nombre", "Quebrada Baquedano", "Quebrada El Toro", "Quebrada El Carrizo" and "Quebrada Jardines del Sur", which helped cause the flood of 1991. The coastal edge of Antofagasta is rocky and steep, so there are no natural beaches, the majority being artificial. Just north of the city, natural beaches extend to the areas of "La Portada", "Las Losetas" and "La Rinconada". Within the water resources of the commune, there are different dry lakes (salar), among which include the Salar de Pajonales, Salar Mar Muerto, Salar Punta Negra and the Salar de Navidad.

The main land route connectivity in the province is Route 5-CH, which connects the city with the rest of the country and is part of the Panamerican Highway. This route connects to the city by Route CH-26 in the north of the city, and Route CH-28 to the south. In addition, the city is connected to the north of the country by Route 1-CH, a way that also allows access to Andrés Sabella Gálvez International Airport and the natural monument La Portada. Vehicular traffic is concentrated around the main avenues of the city due to the long and narrow shape of the urban area. The only avenue that crosses the city from north to south, corresponds to the coastal route known as Avenida Costanera, which is formed by the avenues Jaime Guzmán, Ejército, República de Croacia, Grecia, José Manuel Balmaceda, Aníbal Pinto, 7º de Línea and Edmundo Pérez Zujovic; these avenues provide access to places including Mall Plaza Antofagasta, the Campus Coloso of the University of Antofagasta, the city hall of the Municipality of Antofagasta.

Andrés Sabella Gálvez International Airport is the only airport in Antofagasta and is located in Cerro Moreno, north of the city. This site, despite being classified as an international airport, operates mostly as a terminal for national flights, with one international airline, LATAM Peru, flying to Lima. In this terminal three domestic airlines also operate, LATAM Chile, JetSMART and Sky Airlines.

The city has a port complex of seven docks, inaugurated by President Carlos Ibáñez del Campo on 14 February 1943 under the name of Puerto de Antofagasta, which consists of two terminals. Terminal 1, consists of the docks 1, 2 and 3, is multi-operator and is managed by the "Empresa Portuaria Antofagasta" (EPA) since 1 July 1998.

• Illustration — Bus of the TransAntofagasta • Illustration — Antofagasta train to Bolivia (FCAB) The higher transportation consists of thirteen lines of minibuses, which correspond to buses with a capacity of fewer than thirty people. The public transport is within a tender and is known as TransAntofagasta. The public transport plan took effect officially on 28 November 2005, replacing the old bus service. The route of these buses finish in the Caleta Coloso (south end of the city) during the year, and during the summer come as far as Balneario Juan Lopez, which is out of town. The lower transport consists of taxis lines, corresponding to a black sedans that make their way through the urban area through fixed routes.

The most important railroad is the Ferrocarril de Antofagasta a Bolivia (FCAB) founded in 1888, during the economic boom of the saltpeter industry. In 1930, FCAB was acquired by Antofagasta PLC, which is part of the Quiñenco commercial group. Unlike other contemporary mining railways, FCAB survived the crash of the natural nitrate sector. It provides a variety of transportation services – most notably, the transport of mining products and consumables such as copper cathodes and sulfuric acid – via a 900 km long rail network that is connected to the Ferrocarril Andino de Bolivia, Ferronor (Chile), and Ferrocarril Belgrano in Argentina (Salta–Antofagasta railway). Its gauge is.

Due to the accelerated urban and demographic growth of Antofagasta during 2000–2010, a commuter train using the current FCAB line is currently under review. The project aims to decongest vehicle traffic by linking the north and south of the city with a direct train line.
