【摘要】 本文以河北省邯郸市电磁波实验观测点为例,介绍了震前电磁波实验研究的观测装置和记录资料。通过对记录信息出现的时间及波形特征的初步分析讨论,认为震前电磁波信息的出现,同距震中100公里左右、M_s≥3.5级地震发生,有一定的对应关系。更多还原

【Abstract】 Taking the experimental observation site of the electric-magnetic wave at Hantan, Hebei, as an example, this paper introduces the observational device and the recorded data for the tentative study of the elcctricmagnetic wave before earthquakes. By preliminary analysis for the occurrence time of the recorded signals and features of the wave form, the paper holds that the occurrence of the electric-magnetic wave signals has some corresponding relation with an event of Ms≥3.5 occurred at an cpicentral distance about 100 km.更多还原
