Abstract The ML≥2.0 earthquakes occured in the Three Gorges area during 2000 to 2005 are spatially and temporally scanned with the method of seismic modulating ratio to find out the potential focal region and high stress concentration zone.The results show that the anomaly of seismic modulating ratio does not occur with the change of time and space, it indicates that the distribution of crustal media in the Three Gorges area is comparatively uniform, the stress level is not high and in a steady state, and there is no high stress concentration zone in this area.
Key words :
Three Gorges area
seismic modulating ratio
anomaly
high stress concentration zone
crustal media
