| 摘 要： | 实时地震定位是地震预警系统中必须解决的关键问题之一.文中在借鉴已有实时地震定位方法的基础上并结合我国台网的实际情况,推导得到一套利用前三/四台P波、S波到时信息进行实时定位的算法.作者选取2000年至2008年问福建省地震监测台网记录到的68个3.0级以上地震对该算法进行验证.研究结果表明,采用文中方法的定位结果具有一...

| Abstract: | Real-time earthquake location is one of the key issues that must be solved in earthquake early warning(EEW) system.In this paper,based on the real-time earthquake location method that is used in EEW systems and the real situation of seismic monitoring network in our country,we deduce a formula that just use the first 3 or 4 stations' P/S wave travel time information.We select 68 earthquakes,occurred during 2000-2008,the magnitudes of which are greater than 3.0,to test this method.Results show that our metho... |
