    • Maximum considered earthquake geometric mean peak ground acceleration (MCEG)

    Metadata Updated: September 15, 2025

    A seismic hazard model for South America, based on a smoothed (gridded) seismicity model, a subduction model, a crustal fault model, and a ground motion model, has been produced by the U.S. Geological Survey. These models are combined to account for ground shaking from earthquakes on known faults as well as earthquakes on un-modeled faults. This data set represents the probabilistic and deterministic values for peak ground acceleration for a grid of points with a spacing of 0.1 degrees in latitude and longitude.
