Seismic hazard assessment is very important for determining seismic fortification grade of engineering projects,making urban planning and reducing earthquake disasters,etc.Due to some drawbacks of traditional evaluation methods,it is generally unreliable to assess seismic risk in a certain area by applying these methods.Based on the theory about the brittle failures of multiple locked patches in a seismogenic fault system,an approach to predict characteristic preshocks in a defined research zone is presented by means of self-similarity of rock failures,and then a new methodology to assess seismic hazard is originally established on the premise of the physical prediction of major earthquakes.The Xiongan New Area adjacent to the Yunchengseismic zone is located in the Tangshan seismic zone.According to the analysis on the earthquake trend in the Tangshan and Yuncheng seismic zones and the position relation between the distribution of main faults and the Xiongan New Area,the Baoding research zone is defined within the Tangshan seismic zone,and the Xingtang and Shidu research zones are also defined within the Yuncheng seismic zone.By adopting the above-mentioned approach,major preshocks that will occur in the three zones are predicted.Applying the empirical formulas of seismic intensity presented by some scholars,we evaluate the seismic intensity in the Xiongan New Area when the characteristic earthquake and the preshocks in the Tangshan seismic zone and the preshocks in the Yuncheng seismic zone occur in the future,respectively.The present result suggests that the seismic fortification intensity in the Xiongan New Area in the next 50 years should be adjusted from original 7 degree to 8 degree.
