|Title||Three-dimensional compressional velocity model of the crust and upper mantle beneath Southeastern North America|
|Type||3-D Tomography Earth Model|
|Sub Type||P velocity|
|Short Description||This three-dimensional compressional velocity model of the crust and upper mantle beneath Southeastern North America is derived from the inversion of teleseismic P wave differential travel time anomaly data using RAYTRACE3D, a ray-based tomographic imaging code (Menke, 2005). Travel times were measured from vertical-component P waveforms from 6 magnitude>6 teleseisms seismograms recorded at 205 USArray Transportable Array stations. Sediment-layer and Moho topography corrections were made to the data prior to inversion and crustal structure was held fixed during the inversion. The model is expressed as compressional velocity in km/s. The global AK135 Earth model (Kennett et al., 1995) was used as the staring model in the inversion.|
