Selectivity phenomenon of artificial-source geoelectric field

More Information
  • 地震电信号的"选择性"现象是地电学中非常重要的特征.地电信号的"选择性"现象普遍存在: 上海浦东张江台观测不到源自其西南方向三个接地极上千安培入地大电流的附加地电场, 而能够观测到其正南方向接地极入地大电流的附加地电场; 山东地区邹城台和乳山台无法接收到青州接地极上千安培入地大电流.通过大地电磁测深手段探明了张江台出现该现象的主要原因在于其西南方向信号源至观测台之间地下存在着巨大的高阻体; 其正南方向观测台至信号源之间地下以中低阻体和低阻体为主.上述大地电磁测深资料和断层解释为张江地电场台站观测特征的机理进行了很好阐释, 解释了地震电信号在大区域范围传播过程中由于大尺度地下电性结构复杂性带来的影响, 为深入认识地震电信号"选择性"现象提供了直接的勘探依据.
