Collection of scientific works . Novosibirsk: Nauka Publishing House, 1972 280 with . The studies placed in the collection are aimed at studying the seismic effect manifested in the emission of longitudinal and transverse waves by absolutely rigid bodies of their movement in an infinitely elastic medium. The need for such research is dictated by the requirements of the practice of seismic surveying and seismological research. When seismic waves are excited, non-explosive sources are often used in the form of sufficiently strong bodies moving in a seismic-geological environment, and, consequently, emitting seismic waves to this environment. In this regard, there is a need to study the influence of the mass of such an inertial source and its distribution in space on the seismic effect that the source creates in its environment. Currently, the requirements for measuring equipment are increasing due to the need to measure the dynamic parameters of seismic waves. This makes it necessary to study the interaction, for example, of a device (seismic receiver) with a seismic wave falling on it. Such interaction in our opinion can be studied by studying the motion of a sufficiently rigid body in the field of seismic waves. The study of this interaction is also very useful in connection with the need for a detailed study of the physical basis of the diffraction of seismic waves on rigid geological bodies. In particular, the question of setting boundary conditions when it is possible to move a rigid object of diffraction under the action of elastic waves falling on it is still not sufficiently studied. The collection is divided into two parts .. This separation of material is based on the method of determining the cause of the movement of the body in an elastic medium ..
