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.
