摘要

结合2010年至2011年国外发生的M>6.0、山西地区4.0级以上地震,对山西代县地震台数字化形变观测资料进行系统研究,分析其映震情况和映震特征。研究发现,在多次中强以上地震前几小时至几天左右,各测项均记录到固体潮畸变、高频脉冲、抖动、转折等异常形态。
Combined earthquakes of M>6.0 occurring aboard and earthquakes of M>4.0 in Shanxi region,study on observation data,whose earthquake reflection status and earthquake reflection characteristic are analyzed,of digital deformation at Daixian,Shanxi seismological station is made.It is found that anomaly shapes of aberrance of solid tide,high frequency pulse,dithering and turn etc.are recorded by each observation item several hours to several days before medium and strong earthquakes.
