【摘要】 云南省区域数字地震遥测台网2000年开始使用新的近震定位程序KMSNN,地震速报的精度和速度都有很大提高。从2000年的姚安MS5.9地震到2003年的鲁甸MS5.0地震,17次大震速报的实践,证明了定位程序KMSNN的可靠性和实用性。本文对云南区域台网近震地震参数的测定方法进行了详细讨论,对2000～2003年间的17次大震速报与大震考察结果进行了比较。更多还原

【Abstract】 Since the location program KMSN-N for local earthquake has been adopted in Yunnan Regional Digital Telemetrical Seismic Network in 2000,a great improvement has been made in the accuracy and speed of quick report for great local earthquakes.The processing for 17 strong earthquakes occurred from 2000 (Yao′an earthquake with M_S=5.9) to 2003 (Ludian earthquake with M_S=5.1) indicates that KMSN-N program is more practical and reliable.We had described the location algorithm in detail and its application in Yunnan Regional Digital Telemetrical Seismic Network.The results of quick report for the 17 earthquakes with M_S≥5.0 have been compared with the field survey.更多还原
