Central and Eastern US Hazard Maps, 1996
This page contains probabilistic seismic hazard maps for the Eastern United States. Twelve maps are presented: peak ground acceleration (pga), 5-Hz spectral acceleration, 3-Hz spectral acceleration, and 1-Hz spectral acceleration
(5% damping), each for 10%-, 5%-, and 2%-in-fifty-years probability of exceedance.
