An Ellipsoidal Plate Motion Model of the Indo‐Australian Tectonic Plate

Journal of Geophysical Research: Solid Earth
We present a class of “ellipsoidal rotation matrices” which can be used to characterize tectonic plate motion; where geocentric Cartesian coordinates travel along paths tangential to the ellipsoid.
