| Abstract: | On the basis of analysis of the continental seismotectonics a relationship between shallow earthquakes and faults is discussed.It is now widely accepted that earthquakes are caused by dynamic spreading of shear rupture zone on a discontinuous plane which is called source fault.Seismic-source faults within the continental plate are characterized by complicated regional variation in styles which depend on the tectonic setting and the geodynamic processes.Two types of seismic-source faults within the continental plate have been suggested: (1) Seismic-source fault of type A is usually consistent with the active tectonic fault existing on the ground and represents a bound ary between tectonic blocks;(2) Seismic-source fault of type B is buried in the crust and determined only by fault plane solutions of earthquakes.It has been found that the movement pattern along the seismic-source faults of type B is different from the mapped active faults on the surface in the extentional regions.Accordingly it is necessary to use different methods for research of the seismic-source faults of the two types. |
