Аnnotation: A morphostructural analysis of the relief and a comprehensive analysis of the self-similarity of the water stream network and seismicity of the Northern Sikhote-Alin and adjacent regions are carried out. A series of monobasic and difference surfaces were constructed, which made it possible to trace the history of the neotectonic development of the region presumably from the Eocene period. It is shown that the formation of the relief in the region occurred in several stages, which was reflected in the formation of the pattern of the stream network. The most intense vertical movements occurred at the early stages of the neotectonic period. In the Pleistocene stabilization occurred, and the amplitude of vertical movements was insignificant. The modern erosion-denudation relief was formed at this time. An insignificant activation of vertical movements occurred at the end of the Pleistocene and Holocene. The analysis of the self-similarity of the regional water stream network, reconstructed on the basis of the DEM. A modification of the previously proposed complex Parameter of River Networks Self-similarity ( PRNS ) is considered. Instead of the parameter of the streams by length distribution (a), we use the parameter in the ratio of the total lengths of stream of each order ( D
