【摘要】 基于江西及邻区测震台网记录的自2009年以来的662次地震事件,采用波形互相关方法计算得到了267对重复地震对。利用其中至少3个台站记录到,且各台波形互相关系数不小于0.8的23对重复地震研究了江西省及邻区的地震定位精度。结果显示:赣南及邻区定位精度优于赣北及邻区,宜春地区定位精度较差。更多还原

【Abstract】 On basis of 662 seismic events recorded by the digital seismic network of Jiangxi province and its adjacent areas since 2009,we obtained 267 repeating earthquakes by using waveform cross-correlation method.From the 267 repeating earthquakes,we selected 23 earthquake doubles with waveform correlation coefficient above 0.8and recorded by not less than 3stations to estimate the location accuracy of digital seismic network the Jiangxi province and its adjacent areas.The result shows that:the location accuracy of Gannan is better than adjacent areas in northern Jiangxi Province and its neighboring region,the location accuracy of Yichun is not well.更多还原
