Seismicity within tectonically active territories is controlled by zones of recent fracturing of the lithosphere. Being composed by seismically active faults of various hierarchic ranks, these zones are structures of the highest hierarchic level; they have a “tree-like” shape pattern in a vertical cross-section and complex fracturing patterns on the surface. As exemplified by the Baikal rift system, the report discusses methods to identify the zone of recent fracturing of the lithosphere and regularities of seismic process at faults of various ranks that compose the zone. Seismic process in the zone is a complex manifestation of spatial and temporal migration of earthquake epicenters of various magnitudes in areas of dynamic influence of faults of various ranks in the zone of recent fracturing of the lithosphere [1]. Modern computer modeling methods provide for revealing complex space-and-time regularities of the process as a whole within the seismic zone. Structural and physical parameters of the lithosphere, faults and seismicity, which should be taken into account in computer modeling of seismic process, are considered.
