| Activity of Main Faults since the Late Pleistocene and Related Geohazard Effects in Southeast of Weihe Basin |
| Weihe Basin is not only one important Cenozoic rift basin, but also one significant seismically active belt belonged to Fenhe–Weihe seismic zone in central China. Xi’an city is located on Weihe Basin, and it is the center of political, economic and cultural of west-ern China. There are many active faults and earth-quakes in Weihe Basin. Huaxian county 8.0 earth-quake in AD1556 is a key earthquake and occurred in the high angle normal faults of Weihe Basin. The seismogenic structure of Huaxian earthquake is still controversial. Huashan piedmont fault is one high angle normal faults and maybe related to Huaxian earthquake. Thus, Huashan piedmont fault is a typical example of study relationship of normal fault and its disaster activities. This paper provide scientific basis for the stability evaluation of Xi'an city to study the relationship between fault activity and its earthquake and others disaster. |
