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 .
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. Chile reaches from the middle of ...
The geography of South America contains many diverse regions and climates. Geographically, South America is generally considered a continent forming the southern portion of the landmass of the Americas, south and east of the Colombia–Panama border by most authorities, or south and east of the Panama Canal by some.
Significant Earthquake Faults and damaging earthquakes over the past century along the South American Subduction Zone [6] South America showing 100-year earthquake shaking projections. [6] The subduction of the Nazca plate below the South American plate along the Chile-Peru Trench is associated with numerous earthquakes. Several of these ...

At the Chile triple junction, near the west coast of the Taitao–Tres Montes Peninsula, an oceanic ridge known as the Chile Rise is actively subducting under the South American plate. Geological research suggests that the South American plate is moving west away from the Mid-Atlantic Ridge: "Parts of the plate boundaries consisting of ...
The Chilean Coastal Range (Spanish: Cordillera de la Costa) is a mountain range that runs from north to south along the Pacific coast of South America parallel to the Andean Mountains, extending from Morro de Arica in the north to Taitao Peninsula, where it ends at the Chile triple junction, in the south.
Topographic map of Chile. 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. In the late Paleozoic, 251 million years ago, Chile belonged to the continental block called Gondwana. It was just a depression that ...
