- Abstract:
- To analyze characteristics of the main active faults in the central Yunan province,we inverted slip rates and lock depths of the main fault zones according to Okada's fault dislocation model based on GPS observations during 1999-2007,2011-2017 and geologic slip rates.Our results are as follows:(1)the strike-slip rate of the Red River fault is about(1.5±1.6)～(4.7±1.5)mm/a and the dip-slip rate is(-3.6±1.6)～(1.9±2.4)mm/a,while the southern segment is more active than other parts.(2)the strike-slip rates of the Nanhua-Chuxiong-Jianshui fault and the Wuliangshan fault are(4.8±1.4)～(6.6±1.6)mm/a and(4.0±1.6)～(5.6±1.5)mm/a,respectively.And the dip-slip rates are(-5.8±1.5)～(1.7±1.8)mm/a and(-0.7±1.5)～(0.2±1.4)mm/a,respectively.(3)the Yuanjiang-Yuanyang and Eryuan-Midu segments of the Red River fault,the Wuliangshan fault zone,and the western part of the Nanhua-Chuxiong-Jianshui fault are locked,with locking depths of 6.8 km,7 km,and 7.2 km,respectively.
