The Pacific and the Nazca plate are separating at an increasing rate of about 122-142mm/year. These are the regions where the rate of tectonic activity is very high.The Nazca Plate and the South American Plate are also converging at a rate of about 62mm/year, being the fastest subduction rate on earth.

Result: Nazca plate forms the southeastern part of the Pacific plate.
