Chile is a long, narrow country stretching along South America's western edge, with more than 6,000km of Pacific Ocean coastline. Santiago, its capital, sits in a valley surrounded by the Andes and Chilean Coast Range mountains.
Chile is located along a highly seismic and volcanic zone, part of the Pacific Ring of Fire, due to the subduction of the Nazca and Antarctic plates in the South American plate.
Late Paleozoic, 251 million years ago, Chile belonged to the continental block called Gondwana. It was just a depression accumulated marine sediments began to rise at the end of the Mesozoic, 66 million years ago, due to the collision between the Nazca and South American plates, resulting in the Andes. The territory would be shaped by millions of years due to the folding of the rocks, forming the current relief.
The Chilean relief consists of the central depression, which crosses the country longitudinally, flanked by two mountain ranges that make up about 80% of the territory: the Andes mountains to the east-natural border with Bolivia and Argentina in the region of Atacama and the Coastal Range west-minor height from the Andes.
Chile's highest peak is the Nevado Ojos del Salado, at 6891.3 m, which is also the highest volcano in the world. The highest point of the Coastal Range is Vicuña Mackenna, at 3114 meters, located in the Sierra Vicuña Mackenna, the south of Antofagasta. Among the coastal mountains and the Pacific is a series of coastal plains, of variable length, which allow the settlement of coastal towns and big ports. Some areas of the plains territories encompass territory east of the Andes, and the Patagonian steppes and Magellan, or are high plateaus surrounded by high mountain ranges, such as the Altiplano or Puna de Atacama.
