Seismic Hazards of the US
Entry ID: Seismic_Hazard_USGS
[ Update this Record ]


Summary
Abstract: The hazard maps depict probabilistic ground motions and spectral response
with 10%, 5%, and 2% probabilities of exceedance (PE) in 50 years. These
maps correspond to return times of approximately 500, 1000, and 2500 years,
respectively. The maps are based on the assumption that earthquake
occurrence is Poissonian, so that the probability of occurrence is
time-independent.

The maps cover all of the U.S. including Hawaii and Alaska along with
other pertinent information related to earthquake hazards.
