【摘要】 将包头自动地震速报系统2013年6月—10月地震自动定位结果与全国地震统一编目进行对比,分析包头自动地震速报系统监控能力,统计该系统对不同区域、不同震级范围地震的漏报率。结果发现,该系统对M 2.0以下地震漏报率较高,对M 4.0以上地震的监控与速报具有实际意义,可为其他地市、县建设自动地震速报系统提供借鉴作用和技术支撑。更多还原

【Abstract】 Through comparing Baotou automatic positioning results with offi cially published earthquake catalog from June to October,2013,the monitoring ability of Baotou automatic earthquake quick report system and earthquake rate of missing report for different regions and different magnitude range earthquake are analyzed in this paper. The rate of missing report for earthquakes with less than 2 magnitude is higher. Monitoring and report for the earthquakes of magnitude 4 or over has the practical signifi cance. This result can provide reference and technical support for the construction of automatic earthquake quick report system in other cities and counties.更多还原
