The Western margin of Chile can be observed on this MEdium Resolution Imaging Spectrometer (MERIS) image, particularly the area surrounding the capital, Santiago, in the center of the image. The snow-capped mountains of the Andes Chain separate the coastal regions from the plains of Mendoza in Argentina. In the bottom center of the image is the large strato-volcano Cerro Nevada. The dark flows on the western flanks of the volcano are likely to be relatively recent basaltic lavas. The subduction zone created by the Nazca Plate colliding into the South American Plate is the cause of extensive volcanism in this area.
