The South American Plate is pushing eastward the Nazca Plate. Continental plates are much thicker that Oceanic plates. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. As a result, the Nazca Plate is melting and heating. The water and gases in andesitic magma account for the explosive activity of andesitic volcanoes, which typically lie dormant for many hundreds or thousands of years.
