| 摘 要： | 提出了一种仅基于单台P波到达后1秒数据的包络特征、最大振幅及P波段地震信号的偏振特性来进行地震快速定位的改进模型和方法。选取山东地震台网58例单台1s的P波记录进行快速定位,并与台网定位结果进行比较,结果表明该方法是有效的,为进一步缩短地震预警时间提供了可能。

| Abstract: | Quick earthquake location is the key technical problem of Early Warning System.In this paper,the authors proposed an improved quick earthquake location method which depends on one second of P-wave record's envelope features,max amplitude and it's polarization.Studying on this quick earthquake location method of 58 times seismic events data recorded by Shandong Seismic Network,compared with Shandong Seismic Network's results,we concluded that it is possible to locate earthquake quickly by only one second of ... |
