Today we visit the Southern Andes near Osorno, Chile. This region of the demonstrates many of the developing and fully developed features of converging plates. We have shallow subduction of the Nazca Plate under the South American Plate. In this particular region, a forearc is beginning to develop as the large accretionary wedge to the West of the city is uplifted.
To the East, numerous stratovolcanoes like Tronador and Volcan Osorno dot the terrain. They result from partial melting of the subducting oceanic plate. The Liquine-Ofqui fault is a large strike-slip fault running through the region at approximately 1000 km in length.
