- Abstract:
-
There exit the unreasonableness that the vertical slip rate of the Huashan Frontal Fault jumpily becomes higher since Holocene when the period is shorter from present.Through reviewing the measuring results of more than 40 fault scarps of the Huashan Frontal Fault,we found that these unreasonable results are close related to the latest earthquake,Huaxian 8 earthquake in 1556.Subtracting the coseismic displacement of the Huaxian 8 earthquake in 1556,we eliminated its amplification effect on the calculated value of activity slip velocity.The calculated result of fault scarps in different periods show steady,which indicates that this processed method is necessary and effective.Finally,we applied this processed method to get a more reliable average value of vertical activity velocity of about 1.56 mm/a in the middle section of Huashan Frontal Fault zone since Holocene.
