摘要
S方法将同一测期一条流动地磁测线各测点的变化叠加,可抑制单个测点的干扰,使可能存在的震磁异常信息凸现。本文研究了安徽省流动地磁测线S异常与邻近地区小震震群活动频次和中强地震的关系;探讨了"震情窗"地区S异常与"震情窗"相关地区中强地震的相关性;讨论了同一测期流动地磁测线各测点δf"同向变化"现象。
method, which superposes the change values of all survey points in same mobile geomagnetic survey line, can restrain the disturbance to single point and stick out the possible anomalous information of seismic geomagnetic field. In this paper the relationships between S anomaly and small seismic swarm, moderate-strong earthquakes in near region are researched, as well as the correlativity between the S anomaly in "seismic window "area and moderate-strong earthquakes in the connected region. At last the "Changes in same direction" phenomenon of δf values for all survey points in same survey line and in same time is discussed.
