Plate motion calculators

 

Calculator for MORVEL 25-plate relative motion angular velocities

 

Calculator for NNR-MORVEL56 56-plate no-net-rotation angular velocities

 

Calculated plate motion output will be given in two formats:

  • Rates in mm/yr and azimuths in degrees CW from north
  • Input for Generic Mapping Tool's psvelo module)
  •
