基于概率统计的地震事件公报评估算法

给出一种基于概率统计的地震事件公报评估算法．选择事件的发震时间、震中经纬度构造特征函数．当特征函数为正态分布时计算事件匹配概率，选择匹配概率大于90%的事件为匹配事件．将该算法应用于国际数据中心（IDC）自动处理与人工分析公报的比较分析．相对于人工分析结果，IDC数据自动处理的匹配率约为79%，误检率约为52.3%．该算法可应用于地震事件公报的日常对比分析、台网监测能力分析、数据自动处理结果评估等领域． 

Seismic event bulletin evaluation based on probability analysis

A seismic event bulletin evaluation algorithm based on probability analysis was proposed.An eigenfunction is constructed with origin time,latitude and longitude of the event.Suppose the eigenfunction obeys a normal distribution,then the event matching probability could be calculated.The events with matching probability greater than 90% were selected as the matching events.Initial application in comparison with IDC SEL3 and IDC REB shows that for automatic processing the event detection ratio is nearly 79% a...
