ANALYSIS OF SEISMIC ACTIVITY AND SEISMIC HAZARD IN PRESELECTED AREA FOR LOW AND INTERMEDIATE-LEVEL RADIOACTIVE WASTE DISPOSAL

In the paper, the seismicity and seismotectonic environments of a area is analyzed, which is preselected for low and intermediate-level radioactive waste disposal. The division of potential seismic source zone is revised. Then the different exceedance probability of peak ground acceleration and seismic intensity is calculated by the method of probabilistic seismic hazard analysis, and the spatial distribution characteristics of peak ground acceleration is analyzed. The results show that the peak ground acceleration is closely related with the potential seismic source zone. On this basis suggestions for the site of radioactive waste disposal is gived.
