    • Ground motion models

    Metadata Updated: January 20, 2026

    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 spreadsheet summarizes the ground motion models selected and weights applied for the ground-motion model for South America.
