The advance in obtaining fault slip rate of strike slip fault-A review

摘要

Slip rate along the major active fault is an important parameter in the quantitative study of active tectonics.It is the average rate of fault slip during a certain period of time,reflecting the rate of strain energy accumulation on the fault zone.It cannot only be directly applied to evaluate the activity of the fault,the probabilistic seismic hazard analysis,but also important basic data for the study of geodynamics.However,due to the nonstandardized process of obtaining fault slip rates for a given strike-slip fault,the results could be diverse based on various methods by different researchers.In this review,we analyzed the main advances in the approaches to obtain fault slip rate.We found that there are four main sources affecting the final results of slip rate:the displacement along the fault,the dating of the corresponding displacement,the fitting of the displacement and corresponding dating results,and paleoslip analysis.The main advances in obtaining fault slip rates are based on improving the reli-ability of the above four main factors.To obtain a more reasonable and reliable slip rate for a given fault,it is necessary to select a suitable method according to the specific situation.
