摘要/Abstract

摘要： 自1976年唐山地震后, 开展电磁扰动观测以来, 全国已建立170余个观测站, 观测频段由初期的宽频带改进为ULF超低频和几KHz至几十KHz的点频观测, 从而减少了干扰, 提高了资料可信度。观测仪器多数改进为数字记录, 有利于资料的分析使用。震例表明, 电磁扰动信息具有不同步性; 异常幅度大小与理论计算和实验室实验结果相近似; 选取ULF频段观测有利于对干扰信息的排除。

Abstract: Electromagnetic disturbance observation has been started after Tangshan M_S7.8 earthquake occurred in 1976, and more than 170 observation stations have been built. Observational frequency value has been changed from wide frequency band to ULF and several kHz or several tens of kHz. It decreases the disturbances and at the same time, the data are more believable. Modern observation instruments more and more adopt digital recording and the data are easier to analyze and process. Several earthquake cases show that the signs of the electromagnetic disturbance do not appear during the earthquake. The amplitude of anomaly is similar to the result of theory computation and experiment. The selection of ULF frequency band is beneficial to remove disturbance.

Key words: Electromagnetic disturbance, Electromagnetic anomaly, Short-impending precursor, Observational station
