The seismic records of borehole-to-borehole me- asurements on frequency of 200 Hz in the mi-crostrain range have been analysed. Microplas-ticity manifestations caused by seismic wave are detected on seismic records. It is the lad-der-like stepwise change in amplitude course in some parts of the seismic trace. The step dura-tion (time plateau) presents the amplitude- dependent time delay that shifts the arrival time and protracts pulse front. The microplastic process occurs owing to the anomalous re-alignment of the internal stresses on the micro-structural defects in "elastic" domain. Result is the useful contribution for improvement of the theory of wave attenuation in the rocks. It can also be used in solving the applied problems in material science, seismic prospecting, diagnos-tics etc.
