Summary
The data for this release is an ASCII file containing grid points of Cascadia P- and S-wave velocity models. The model volume was developed to include the Cascadia subduction zone for purposes of ground motion simulation. The description of the model and background of its development is provided in the associated Open-File Report. The grid points are given in Universal Transverse Mercator (UTM) Zone 10 North coordinates for East and North locations, and the grid point depths are given in meters below mean sea level. Grid point spacing is 500 meters in each ordinal direction. The model region extends approximately from 40.2°N to 50°N latitude, and approximately from 122°W to 129°W longitude. The maximum depth of the model region is [...]
