Аnnotation: The article deals with the results of the first complex geological and geophysical studies of the Sarminsky paleoseismodislocation (PSD). Based on the interpretation of the sections of the trench walls, the analysis of shallow geophysics data (electrical exploration, seismic exploration, GPR) and the morphological profiling of seismogenic relief microforms, a conclusion was drawn on the shear-uplift strain genesis. The planes of displacement of the main reverse faults and thrusts have a northwest fall, the minor ones are southeast. The kinematic characteristics of seismic movements indicate the formation of dislocations in the zone of the Primorsky fault under conditions of subhorizontal compression.
