Generation of electromagnetic field due to resonance between ground velocity and ions motion in the Earth's magnetic field

在地面速度和电磁场同时观测的基础上，我们研究了地震发电机效应，其中与地面速度有关的电磁场的时间变化是由地下水中的离子在地球磁场下的回旋运动引起的。圆极化电场、早于地震波到达的电场探测以及地下水离子在回旋频率下的地速(输入)和电场(输出)传递函数的峰值频率强烈支持地震发电机效应。

Based on simultaneous observations of ground velocity and electromagnetic field, we have investigated the seismic dynamo effect, in which temporal variations of electromagnetic field associated with ground velocity are caused by cyclotron motion of ions contained in groundwater under the Earth's magnetic field. Circularly polarized electric field, detection of electric field earlier than arrival of seismic waves, and peak frequencies of the transfer function between ground velocity(input) and electric field(output) at cyclotron frequencies for ions in groundwater strongly support the seismic dynamo effect.
