Synopsis
Soil-motion records resulting from studies on “soil dynamics” are analyzed. The investigation is restricted to exciter-pickup distances ranging from 10 to 200 ft (microseismics). Periodic and nonperiodic exciter forces are discussed. Surface displacements in the vertical and longitudinal direction (plane trajectories) and combined with the transverse direction (triaxial motions) have been analyzed.
