FIELD: detection of such source of seismic oscillations as earthquake, volcano effusion, cannon shots. SUBSTANCE: method involves receiving angular seismic oscillations and measuring their characteristics with respect to two horizontal orthogonal axes using at least two seismic receivers. Ratio of measured amplitudes of oscillations for each receiver provides direction of front edge of seismic oscillation and bearing to source of seismic oscillations. Bearing results provides data about position of oscillation source. EFFECT: increased functional capabilities. 4 cl
