This tool is used to calculate risk-targeted ground motion values from probabilistic seismic hazard curves in accordance with the site-specific ground motion procedures defined in “Method 2” of 2010 ASCE 7 Standard Section 21.2.1.2.

The USGS collaborates with organizations (such as the Building Seismic Safety Council) that develop model building and bridge design codes to make seismic design parameter values available to engineers. The design code developers first decide how USGS earthquake hazard information should be applied in design practice. Then the USGS calculates gridded values of seismic design parameters based on USGS hazard values in accordance with design code procedures. The U.S. Seismic Design Maps application provides seismic design parameter values from the following design code editions: 2013 ASCE/SEI 41, 2012/09/06 International Building Code, 2010/05 ASCE/SEI 7 Standard, 2009/03 NEHRP Recommended Seismic Provisions, 2009...

The comma-separated values (CSV) files below provide maximum and minimum SS, S1, and PGA values for each of the 50 states (plus Washington, D.C.), 3,222 counties, and most* of the 32,236 ZIP codes in the U.S. Geographic coordinates of these maxima and minima are also provided. The values and coordinates are based on the earthquake ground motion maps in, equivalently, the 2009 NEHRP Recommended Seismic Provisions, the 2010 ASCE-7 Standard, and the 2012 International Building Code.
The National Seismic Hazard Model (NSHM) and Seismic Design Maps are a suite of products primarily aimed at improving earthquake-resilient construction in the United States by providing information about potential ground shaking caused by earthquakes. The NSHM is updated every six years to provide the basis for the Seismic Design Maps used in building codes.
