Each of the downloadable files below contains spectral response accelerations at 22 periods on a grid of latitudes and longitudes that cover this geographic region. See the parent item for how Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations are derived from the data in these files.

Each of the downloadable files below contains peak ground accelerations on a grid of latitudes and longitudes that cover this geographic region. See the parent item for how Maximum Considered Earthquake Geometric Mean (MCEG) peak ground accelerations are derived from the data in these files.
The Maximum Considered Earthquake Geometric Mean (MCEG) peak ground acceleration (PGA) values of the 2015 NEHRP Recommended Seismic Provisions and the 2016 ASCE/SEI 7 Standard are calculated from the data in the downloadable files below, via the following equation: PGA = min[ PGAUH , max( PGAD84th , 0.5 ) ] where PGAUH = uniform-hazard peak ground acceleration; PGAD84th = 84th-percentile peak ground acceleration. These peak ground accelerations are each for the geometric mean of two horizontal components and a site shear wave velocity (VS30) of 760 m/s. For more information, see the "Related External Resources" below. Note: The USGS Seismic Design Web Services first spatially interpolate...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
