Abstract: The invention is a polarized seismic wave generator used within a cavity for propagating polarized acousto-elastic shockwaves into surrounding cavity strata. The invention comprises segments with orient-able acousto-elastic shockwave sources, the segment also having shockwave mitigation material. Each shockwave source is configured to generate acousto-elastic shockwaves into surrounding cavity strata, whereby the shockwave mitigation material decouples the generated wave fields. Each segment is constructed to fix the relative azimuthal orientation and vertical inclination of the acousto-elastic shockwave sources. The invention also comprises a frame with a major axis oriented in a vertical relationship with respect to the cavity, the frame holding each segment in a fixed position relative to other segments within the cavity.
