Location Accuracy Estimating of the Digital Seismic Network of Jiangxi Province and Its Adjacent Areas Using Repeating Events

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 0.8 and recorded by not less than 3 stations 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.
