This patent describes a system for monitoring changes in azimuth due to shifts in geological features of the earths surface, using a collimated laser beam which is split and reflected from a plane mirror and a prismatic mirror to target area showing translational and rotational changes in the mirrors location. The beam is directed to a second pair of mirrors at an angle to the beam which will verify the location movement, source or target. Author
