The vertical component of the electric field strength and atmospheric current variations accompanying strong earthquakes with a magnitude of more than six are analyzed on the basis of instrumental observations carried out at the Mikhnevo Geophysical Observatory and at the Center for Geophysical Monitoring in Moscow (Sadovsky Institute of Geosphere Dynamics, Russian Academy of Sciences). It is shown that the strong earthquakes cause alternating sign–time variations of the electric field or its baylike variations of positive or negative sign at significant distances from the earthquake source. In the same time, earthquakes cause variations in the atmospheric current in the form of an increase in it or alternating sign–time variations of the averaged amplitude. The present results supplement the corresponding database and may be of interest in improving the known and developing new models of the effect of earthquakes on the environment and their verification.

电场和大气电流对强地震的远程响应

在米赫涅沃地球物理天文台和莫斯科地球物理监测中心（萨多夫斯基研究所）进行的仪器观测的基础上，分析了伴随 6 级以上强地震的电场强度和大气电流变化的垂直分量。地圈动力学，俄罗斯科学院）。结果表明，在距震源很远的地方，强地震引起电场的交替符号-时间变化或其正负号的海湾状变化。同时，地震引起大气电流的变化，表现为平均振幅的增加或交替的符号时间变化。
