ITRF2014 Velocities

Table of latest station velocities (not yet linked)

An example of ITRF2004 horizontal velocities estimated from the combined time series of JPL and SIO. Significant (M>6) earthquakes denoted by red circles. This is a screen shot from MGViz, our new interactive project interface

 

Estimates of the east (blue circles), north (red circles), and up (gold circles) velocity components are compared between JPL (plotted on the horizontal axis) and SIO (plotted on the vertical axis).  If the JPL and SIO estimates were identical, then all the circles would plot along a 45° line. We conclude that the JPL and SIO estimates are close for nearly all GPS sites. There are 1690 GPS sites on the plot, all with at least 10 years of data.
