A research method and parameter C_v which depicts the spatial inhomogeneity of earthquakeprecursory group, are developed in the paper. The influences of factors, such asinhomogeneous distribution of p
It is proposed that some possible macroseismic epicenters can be determined quickly from the relationship that the microseismic epicenters located by instrument
To understand precursory phenomena before seismic fault sliP,this work focuses onearthquake nucleation process on a fault plane through numerical simulation.Rat
