ABSTRACT
Uniform-hazard ground motion maps and shapefiles prepared for horizontal spectral accelerations (SA) at 0.2-second, 1-second, and 5-second period, with a probability of exceedance of 2%, 5% and 10% in 50 years, for NEHRP soil site class B/C (VS30 equal to 760 m/s). Uniform-hazard ground motion maps and their underlying GIS data were prepared for PGA and horizontal spectral accelerations at 0.2, 1.0, and 5.0 second period, with a probability of exceedance of 2%, 5% and 10% in 50 years, for NEHRP soil site classes B/C and D (VS30 equal to 760 and 260 m/s, respectively).
