The Grouping of the Strike-Slip Offset Data and Its Relation with The Seismicity Along Middle Segment Of the Xiaojiang Active Fault

摘要

The data of the strike-slip offset along the Xiaojiang active fault can be obviously grouped. The groups of small orders of magnitude data within 100 m show clear linear characteristics of increments between 8 m and 12 m, which indicates that the segments of the Xiaojiang active fault is of characteristic seismicity and the distribution of the values of each group indicates that there are smaller earthquakes and creep between two large earthquakes along each segment of the Xiaojiang active fault. The interval between two characteristic large earthquakes can be calculated with the increments for two groups of slip data and the slip rate of the fault.
