摘要:
以云南地区的地震数据为基础,借鉴国内外P波震相自动识别相关研究,提出一套可实时处理P波震相的方法,即STA/LTA和贝叶斯BIC双步骤捡拾法。应用此方法对所选取的云南强震动台网观测记录进行P波自动精确识别,并与人工捡拾方法结果进行对比,确定STA/LTA和贝叶斯BIC双步骤捡拾法的识别精度能满足地震预警快速准确的要求。
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.
