Homeland Infrastructure Foundation Level Data HIFLDUniform-hazard ground motion data prepared for peak ground acceleration (PGA), 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).FileengPennsylvania Spatial Data Access (PASDA)PublicSeismic Hazard Model PGA with 2 5 or 10 Probability in 50 years [Pennsylvania]DatasetsPennsylvania
