Service Description: This data is a compilation of shear-wave data from studies performed by the Washington Geological Survey, the U.S. Geological Survey, and the Environmental and Engineering Geophysical Society. This dataset contains one feature class providing strong-motion sensor site locations and two related GIS tables that provide S-wave and P-wave velocity data obtained from those sites.
Shear wave data are used to quantify and classify the National Earthquake Hazard Reduction Program (NEHRP) site-class data and to construct accurate ShakeMaps in Washington and Oregon. This data is also used to refine ground-motion prediction equations for Pacific Northwest earthquakes.
