Soloviev] A model of block-and-fault system dynamics (a block model) has been developed to analyze how the basic features of seismicity depend on the lithosphere structure in a region under consideration and on the peculiarities of the lithosphere dynamics. The lithosphere in the region is modeled by a system of perfectly rigid blocks divided by infinitely thin fault planes. The viscoelastic interaction between the blocks and with the underlying medium is specified. Displacements and rotations of the blocks at each time are determined so that the whole block system is in a quasi-static equilibrium state. When the ratio of the stress to the pressure exceeds the critical level in some part of a fault zone, a stress drop occurs that is considered in the model as an earthquake. The paper contains a review of results obtained by numerical simulation of the dynamics of different block structures including the structures approximating the lithosphere structure in specific seismic regions. These results suggest that the block model is a useful tool for studying the influence of geometry of faults and motions of blocks on seismicity features.
