Research into Fault Motion in Sichuan-Yunnan Region, China Incorporating Earthquake Risk Analysis
Abstract eng: We have analyzed the characteristics of main faults in terms of slip rates in Sichuan-Yunnan region, China based on GPS measurements in the period of 1997-2007. Dividing the study area into 12 tectonic blocks separated by faults suggested by geological investigation, we derived the Euler vectors of individual blocks and relative Euler vectors of block-pair for adjoining blocks by GPS velocity of GPS stations throughout. The slip rates of individual active faults were calculated, and their motion styles were analyzed in detail. We find that the linking section between the Xianshuihe and the Anninghe fault appears sharp motion variation, possibly implying high seismic risk there. Besides southwestern portion of Longmenshan fault also needs much attention to be paid on due to the great impact by the quick slip of Xianshuihe fault.
