Euler Pole Calculator (EPC)
DESCRIPTION
The EPC software calculates velocities for any points located on the earth’s surface given the Euler pole parameters and estimates the Euler pole parameters given the observed velocities of a set of sites located on a tectonic plate. Since version 2, the software is able to estimate or apply the Plate Translation Rates, as well.
