峰度和AIC方法在区域地震事件和直达P波初动自动识别方面的应用
|
摘要
提出了一种基于直达P波信号的峰度和Kurtosis-AIC方法进行区域地震事件实时检测和直达P波初动精细识别的新方法,并应用于山东地震台网记录的地震波资料处理.结果表明:(1)应用峰度方法能够有效识别出地震事件,可有效减低地震事件的错误报警率和漏报率;(2)与人工识别震相到时的结果相比,根据Kurtosis-AIC震相自动识别方法得到的震相到时的平均绝对值误差为(0.09±0.08)s。
Basing on Kurtosis-AIC and kurtosis methods of P-wave signal,we put forward a new method for real-time detection of regional earthquake event and automatic identification of direct P-wave first motion and apply it to process seismic data recorded by Shandong Seismic Network.The results show as follows:(1)The kurtosis method effectively detect earthquake events,and may effectively reduce false alarm and missing report rates;(2)Compared with phase arrival time results in manual identification,average absolute error of phase arrival time in automatic identification based on Kurtosis-AIC method is(0.09±0.08)s.
