Establishing recent displacements along faults is an important and delicate task. Larger
faults are accompanied by broader fault zones that require a specific approach to geodetic
measurements of fault block displacements. The vector of fault block displacements, or
resultant, is a vector sum of differential displacements within the fault zone. For the purposes
of recording the displacements we propose the stabilization of a geodetic network of
points positioned in fault blocks outside the fault zone, whereby the displacements would
be manifested in the deformation of the network. The resultant displacement vector can
then be derived from the latter deformation, and from that, the dip and strike of the fault
zone as well as the extent of the displacement.
