【摘要】 运用双差定位法对2014年云南鲁甸6.5级地震序列余震进行重新定位,得到565次小震的精确定位结果。根据小震丛集性原则,求解发震断层参数的数学模型,运用模拟退火全局搜索和高斯牛顿局部搜索相结合的方法对地震发震断层面参数进行反演,得到鲁甸6.5级地震断层面的走向、倾角分别为160.8°和89.1°,并对其构造环境进行了分析。更多还原

【Abstract】 We relocated the aftershocks of Yunnan Ludian MS6. 5 earthquake in 2014 by using the double-difference location method,and obtained the accuracy location results of 565 earthquakes. According to the principle of small earthquakes cluster,we solved the mathematical model of the seismogenic fault parameters. By using the method of combining the simulated annealing global search algorithm with Gauss-Newton local search,we inversed the parameters of fault plane to obtain the strike, and the dip of fault plane which are 160. 8° and 89. 1°separately. Then we analyzed the tectonic environment of Ludian MS6. 5 earthquake.更多还原
