Model Strain Rates

    Principal Strain Rate Axes (format explanation):

    Strain Rate on 0.6°x0.5° mesh spacing:     Second Invariant of Strain Rate, for contouring purposes:     Predicted Focal Mechanisms, in GMT format:


Model Velocities and Rotated Observed Velocities

    Rigid Plate Angular Velocities (Rotation Poles), GSRM Pacific plate frame: rotation_vector_plates_PA.dat
    Angular Velocities obtained to rotate Geodetic Studies, GSRM Pacific plate frame: rotation_vector_studies_PA.dat
    Rotated Observed GPS Geodetic Vectors, caveat and selection of any GSRM frame
    Model Velocities, 1°x1° grid, in GMT psvelo -Se format; 1-sigma velocity uncertainties are zero for points in rigid plates or exactly at the rigid plate/plate boundary zone interface and non-zero uncertainties in the plate boundary zones reflect those for velocities relative to the Pacific (PA) frame (all files are about 1.9 Mb, or about 0.6 Mb compressed):
