Two methods of direction finding of geosphere sources of oscillations and waves of infrasonic and low-frequency sound ranges by laser strainmeters are considered. The first method is based on the assumption that the recorded wave disturbances refer to surface waves of the Rayleigh type. In this case, a two- coordinate laser strainmeter is used, which consists of adjacent one- coordinate laser strainmeters with mutually perpendicular measuring arms. In the second case, the triangulation method is used. This method uses a minimum of three spatially separated laser strainmeters.
