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
