- Abstract:
-
Used the domestic and overseas researches of P wave seismic phase identification for reference,a real-time processing method for P wave seismic phase identification is proposed based on seismic data of Yunnan area. The method is STA/LTA+BIC two-step pick-up method,by which the selected records of P wave from Yunnan Strong Motion Observation Network were accurately and automatically identified. The differences between this method and the artificial pick-up method were compared and analyzed. The results shows that the precision of STA/LTA+BIC two-step pick-up method can meet the rapid accurate earthquake warning requirement.
