| 摘 要： | 东部地区的数字化地震台网在定位西部地区的某些地震时总产生偏差,这一现象很普遍。本文利用中国地震局2001~2003年测定的中国西部地区(云南、四川、甘肃、青海、新疆、内蒙古)地震,比较上海数字地震台网的大震速报结果,对上海数字地震台网在地震定位方面存在的一些问题进行分析与处理,进而加深速报人员对西部地区地震记录特点的理解,提高东部地区的地震分析人员对西部地震的速报精度。

| Abstract: | It is a universal phenomenon that there is always deviation in locating some earthquakes occurred in the western area using earthquake records of digital seismic network.In the paper,the western area's earthquakes measured by Chinese Seismic Bureau between 2001 and 2003 are compared with the quick location results of Shanghai Seismic Network.Through analysis and discussion on earthquake location,some problems are found and earthquake record's features of west area are more deeply understand.Our purpose is to improve the location precise of the earthquakes occurred in the western areas. |
