ETQ post-seismic ground motion map

ETQ post-seismic ground motion map

Surface displacement (in the horizontal plane) map of the Earth associated to tectonic (e.g. earthquake) deformation. The product is suited to document surface deformation at the scale of a fault system. The displacement map is produced using image matching techniques (sub-pixel image correlation) applied to multispectral imagery.
