Аnnotation: The article describes ways to estimate and restore irreversible deformations that occur in the epicentral zone after destructive earthquakes, using velocimeters. An analytical model of residual displacement is proposed, which can be used to model displacements in synthesized accelerograms. The operation of installing residual displacements into waveforms of simulated soil movements is briefly described. According to the proposed model, it is possible to estimate the residual displacements. Examples of the restoration of residual displacements recorded by a velocimeter on a vibroplatform are given. A simple algorithm for estimating residual displacements based on interactive filtering of a long-period trend is described. The algorithm is implemented in the time domain and takes into account the amplitude-frequency characteristic of the velocimeter. The efficiency of the algorithm was tested on a synthesized accelerogram containing residual displacements, and the algorithm was applied to the records of explosions.
