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. These data are intended to summarize the available quantitative information about seismic ground motion hazard for South America. 2017 publication date Complete None planned -85.0 -20.0 15.0 -70.0 none Seismic Earthquake Hazard Risk USGS Metadata Identifier USGS:598cb3e4e4b09fa1cb109202 http://geonames.usgs.gov/ Argentina Bolivia Brazil Chile Colombia Ecuador French Guiana Guyana Panama Paraguay Peru Suriname Trinidad and Tobago Uruguay Venezuela South America none 2017 None Acknowledgment of the U.S. Geological Survey, National Seismic Hazard Mapping Project would be appreciated in products derived from these data.

The following report provides information on quality assessment for the data set: Petersen, M.D., Harmsen, S.C., Jaiswal, K.S., Rukstales, K.S., Luco, Nicolas, Haller, K.M., Mueller, C.S., and Shumway, A.M., 2018, Seismic Hazard, Risk, and Design for South America: Bulletin of the Seismological Society of America, doi: 10.1785/0120170002 The sum of model weights equals 1.0 Data are complete. Active crustal earthquakes are modeled using five alternative ground motion models (GMMs) from the Next Generation Attenuation (NGA)-West2 project; earthquakes in the stable continental region or craton are modeled using eight GMMs; subduction interface earthquakes are modeled using three GMMs; and deep gridded seismicity is modeled using four GMMs. Weights applied to the GMMs are the same as those developed for the USGS National Seismic Hazard Model for the conterminous United States. 2017 agrids Gridded earthquake rates (a-grids), for a grid of points equally spaced in latitude and longitude.
