2 Conclusion
Fenghuangshan-Tianshui fault is a Holocene active fault. It laterally slips at the average rate of 1.1 mm/a during 6.4 ka and vertically slips at the average rate of 0.37 mm/a and 0.16 mm/a since the time 16.6 ka and 6.4 ka before respectively. Diaogoumeng-Dongjiawan segment has occurred an abrupt event in the period of 6.4 ka BP, which is assumed to be related to the 734 Tianshui M=7 earthquake, but further work is still necessary.
