Data Description: Uniform background zones, special zones, finite fault sources and hazard probability layers for the CEUS. These zones were defined for U.S. Geological Survey Open-File Report 2008-1128, Documentation for the 2008 Update of the United States National Seismic Hazard Maps. The TIFF-format surfaces present ground motions for various probability levels.

Data Summary: Data layers were compiled from source ASCII text files of latitude and longitude to define polygon and polyline boundaries. Text files that represent each uniform background zone were merged to create a single polygon GIS layer. Data are presented in geographic coordinates on the North American Datum of 1983.
