利用空间电场和大地磁场变化设计的地震临震预报器

地震临震预报器由二路电子指南针、三路AM接收器、一路FM发射接收器一路次声波接收装置及短波收音机组成。是基于这样的事实:2008年5月12日,地震前13分钟,北川中学(1)班上物理课时发现,教具指南针左右摆动不能稳定,地震前电磁异常现象磁电效应是由地震引起的的主要因素,地震前电磁异常由大量实例证实。1976年7月28日唐山市7.8级地震,中国前几天,唐山的许多电台故障及其邻近地区,声音忽大忽小,有时不能被接收,日光灯自己点亮等地震前空间电场异常也由大量实例证实,在当今世界上地震频繁,破坏力很大。如果地震前几个小时,知道地震发生时,可以避免许多可怕的事情。地球是一个复杂的巨系统,建立一个非常精确动力学方程是无法实现的。利用空间电场和大地磁场变化设计的地震临震预报器,该电场、磁场参数测量是不必要的进入地球内部,技术上容易实现,制成的地震预测器由软件、硬件构成,主要由AT89C2051单片机和霍尔效应传感器。AM、FM接收机电路和单片机测量峰值电压,比较参考电压组成。临震动力学方程、电磁场规律建立是非常复杂的,但利用空间电场和地球磁场变化的设计地震临震预测控制系统很简单。

Abnormally large short-term and impending earthquake geomagnetic anomaly implies a possibility of earthquake pre-warning

The study found that strong magnetic anomalies repeatedly took place before big earthquakes. Based on geomagnetic record analysis results,we discussed a possible pattern of the magnetic anomalies prior to earthquake. In meizoseismal area or epicenter,in a time period of 36 h to about 10 min before earthquake,the exceptional big geomagnetic change increases with the magnitude of earthquake. We calculated that,in a place of 1 km from the epicenter,the magnetic anomaly before destructive earthquakes of Ms 6～9 can reach to 102～104 nT(the magnitude of earth magnetic field is 104 nT) ,rather than the magnitude of 10 nT from seismomagnetic effect theories since 1960s. From this we speculated the abnormal magnetic ULF near epicenter before earthquake seems to be an "intermittent magnetic eruption". Accordingly,we proposed that geomagnetic induction earthquake alarm can be a new pre-warning method to surmount hardship in solving the puzzledom of earthquake imminent prediction.
