摘要
The method involves determining arrival time of a shearing wave (S) at the level of a triaxial sensor by projecting a seismic signal in a new location along propagation direction of a compression wave (P) and perpendicular axes (Np, B), and automatically detecting the arrival time of the shearing wave by applying a signal analyzing method to the projected seismic signal in a plane defined by the axes. A spatial origin of a seismic event is located from the compression wave propagation direction and the arrival time of shearing and compression waves.
