A 7.8 earthquake rattled northern Chile on June 13, 2005, at 6:44 PM local time, killing 11 and leaving hundreds homeless, according to the Associated Press.

The large quake shook much of South America and was felt in Brasilia, Brazil, approximately 2,400 kilometres to the east and in Santiago, Chile, 1,515 kilometres to the south.
The most damage occurred near the earthquake’s centre in the rural, mountainous section of the Tarapaca Province, where the shaking triggered landslides and flattened houses.



This topographical image of northern Chile shows the geology that produced this earthquake. The centre of the earthquake is represented with a plus sign in the image. To the east, pink represents the higher elevation of the mountains, with the highest peaks tipped in white.
Among the tallest is the 5,995-metre-high Cerro Sillajhuay on the border with Bolivia.
The steeply changing elevation and folds in the land around the earthquake’s centre make it easy to see why the earthquake caused landslides. To the west of the centre, the land gradually flattens into the flat Pampa del Tamarugal, a broad green ribbon of low-elevation land.

Far to the west of the region shown here, the Nazca Plate (a section of the Earth’s crust that carries part of the Pacific Ocean) pushes steadily under the South American Plate, pushing up the Andes Mountains along the western edge of South America. Earthquakes happen frequently where sections of the Earth’s crust collide, and Chile is particularly prone to geologic activity.
The same conditions that give rise to earthquakes have also produced some 620 volcanoes throughout the country. The June 13 earthquake occurred east of the plate’s surface boundary, near the base of the Cordillera Occidental, a range of the Andes. The quake was centred deep in the Earth, 119 kilometres from the surface, where the land is being forced up by the now subducted Nazca Plate.

This topographical image was created using data from the Shuttle Radar Topography Mission (SRTM).
SRTM was designed to collect three-dimensional measurements of the Earth’s surface using a radar instrument that flew aboard the Space Shuttle Endeavour in February 2000.

A powerful 7.9-magnitude earthquake shook Chile's northern mining region on Monday, causing at least eight deaths, cutting power and driving residents from their homes in the port city of Iquique.

The quake was also felt in the coastal cities of Arica and Antofagasta, in Chile, in the Bolivian capital, La Paz, and in southern Peru.
Acting Chilean Interior Minister Jorge Correa said on Chilean television one man was confirmed dead in a landslide triggered by the earthquake.
Five others died after their car was crushed by a falling boulder on a mountain road near Iquique and two more died of undisclosed causes.
Authorities said the region suffered power cuts and that telephone communication was down in the area.

"Police, fire and other civil protection agencies are in the area evaluating the situation" – ONEMI, Chile's national emergency centre.
"There is no chance of a tsunami" - analysis by Chilean naval oceanographers who said the epicentre was in the mountains, not in the ocean.

Local television reported that Iquique, which has a population of about 140,000, and the popular seaside resort of Arica, were most affected.
Hotels in Iquique could not be reached by telephone for comment despite repeated attempts.
ONEMI said the epicentre of the quake was 70 miles northeast of Iquique but was felt throughout northern Chile, a zone of heavy mining activity.

A source at Chile's state-owned Codelco, the world's top copper producer, said the company's operations in the region had not been affected.
"Operations have not been stopped, they remain the same"
Other international mining companies with operations in the region could not be reached for immediate comment.

The quake occurred at 6:44 p.m. local time (2244 GMT) and lasted nearly a minute.
