Comparison with the 1999 Global Seismic Hazard Assessment (GSHAP) model

A comparison of the 2017 USGS South America seismic hazard model and the 2010 USGS South America seismic hazard model was made to see how the models differ. The comparison was made as the ratio of PGA at 10% probability of exceedance in 50 years.
