摘要
以2007年11月15日6时5分23秒和37秒在山东泗水接连发生的ML3.1和ML3.3两次地震为例,分析研究了地震叠加如何快速定位的问题。研究结果表明,在大震速报中,可以根据测定的第1个地震的三要素参数,直接确定后一次地震的震中经、纬度,第2个地震的发震时刻等于第1个地震测定的发震时刻加两PG到时差,第2个地震震级等于第1次地震多台测定的震级加上任一单台测定两次地震震级差。
There were two earthquakes with ML3.1 and ML 3.3 occurred separately in SiShui,Shandong on 06:05:37 and 06:05:37,Nov.15,2010,how to locate the earthquake quickly were researched in the paper.The result show,the second earthquake location can be measured by the first earthquake's result,and the occurring time of the second earthquake is equal to the occurring time of first one plus the difference of the two quake's travel time;the magnitude is equal to the magnitude of the first one plus the difference of the magnitude measured by either of the stations.
