摘要

Peculiarities of seismic waves generated by small meteorite falling with cosmic velocity on the Earth surface are discussed. The pick value of the force by the fall, the duration of interaction and the approximate mean of a seismic oscillation level near the epicenter are evaluated. The estimations of the maximum of oscillation displacements in the pulse seismic responses of the longitudinal, transverse and surface waves are given by the use of the simplified model of elastic homogeneous half-space and in the supposition of vertical direction of the fall and on the distances from the epicenter corresponded to far wave zone. The parameters of seismic wave pulse responses are investigated on the base of numerical calculations of the integral expressions used by their description.
