| 摘 要： | 为了全面评估区域数字地震台网实时速报系统对网缘地震（网内边界至边界线外100公里）的自动处理能力，我们将福建台网在2000年1月至2007年12月所编目的1074个网缘地震记录转换为模拟实时波形数据流，对系统功能进行测试与分析。测试结果表明：1.系统基本具备福建台网网缘地震的自动速报能力，速报震级下限可达ML3.0级；2.系统对86.4%福建台网网缘地震自动定位的精度小于15公里，96.2%网缘地震自动定位的精度小于30公里；3.系统对99.6%福建台网网缘地震的震级自动测定偏差不大于0.3级。以上主要结论在2008年8月21日云南盈江M5.9级地震序列的实时速报实践中得到检验。 |
