The geology of Chile is a characterized by processes linked to subduction, such as volcanism, earthquakes, and orogeny. The building blocks of Chile's geology were assembled during the Paleozoic Era when Chile was the southwestern margin of the supercontinent Gondwana .
The Chile Ridge, also known as the Chile Rise, is a submarine oceanic ridge formed by the divergent plate boundary between the Nazca plate and the Antarctic plate. It extends from the triple junction of the Nazca, Pacific , and Antarctic plates to the Southern coast of Chile .
In 1927, the service was placed under the Department of Geophysics (DOG) by the University of Chile. [7] In 2013, its name was officially changed to Centro Sismológico Nacional (CSN). [8] After an earthquake on April 21, 2007 in the Aysén Region, the national authorities were in dire need of an emergency plan in case of earthquakes and tsunamis.
Chile is situated in southern South America, bordering the South Pacific Ocean and a small part of the South Atlantic Ocean. Chile's territorial shape is considered among the world's most unusual; from north to south, the country extends 4,270 km (2,653 mi), and yet it only averages 177 km (110 mi) in width.
The Valdivia fracture zone (VFZ) is a transform fault zone off the coast of southern Chile which runs between the continental slope near Valdivia in Chile and the Panov Seamount crossing the Chile Ridge. Map of the several segments of Chile Ridge which is divided by numerous transform fault zones, including Valdivia fracture zone. The segment ...

Studying sites at the tip of South America adds context to bigger questions about climate patterns, said Tom Lowell, a co-researcher and geologist who first went to this area of Chile in the late ...
The Chile triple junction, a geologic junction off the southern coast of Chile where the South American, Nazca and Antarctic tectonic plates meet. The Chile triple junction (or Chile margin triple junction) is a geologic triple junction located on the seafloor of the Pacific Ocean off Taitao and Tres Montes Peninsula on the southern coast of Chile.
