Schema
uniform hazard ground motion / US PGA 2Pct50Yrs BC poly / v1.0.0
Schema from us-pga-2pct50yrs-bc-poly.parquet, gcs-hifld-next-datasets-prod, v1.0.0.
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).Full dataset can be downloaded from: 04.
