Discussion on several important problems in earthquake-related electromagnetic disturbance monitoring in China

摘要

Earthquake-related electromagnetic observation aims at finding abnormal electromagnetic variation associated with earthquake possibly.The existing studies have proved that this method is,to a large extent, effective in short-term and impending earthquake predication.This paper summarizes progress and discusses some related problems in this field.Some requirements for observation system have been proposed to improve monitoring level.As a case observation using the reformed observation system in Jinghai seismologic station, Tianjin,some results are given.
