Study Locations
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This feature class contains 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. 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.</SPAN></P></DIV></DIV></DIV>
