【摘要】 介绍了在2013年7月22日甘肃岷县漳县MS6.6地震前/后地电学科所做的震情研判和预测预报工作,评价了震中附近甘东南及邻区台站出现的地电阻率观测数据异常。认为:(1)在地震短临阶段和紧接震后提出的两个地震预测意见大致符合本次地震主震、余震发生的实际情况;(2)在数据异常中包括了与本次地震有关的前兆异常信息和由于台站观测环境变化引起的干扰数据异常,震前震后的震情预测意见有一定程度的有科学意义和启示,也存在明显的不确定性。最后强调了加大力度保护地电观测环境的重要性。更多还原

【Abstract】 This paper presents geo-electrical research in earthquakes and their forecasting performed prior to and immediately following the Minxian-Zhangxian MS6.6 earthquake and appraises the observation data anomalies in apparent resistivity that appeared at stations in southeastern Gansu and its adjacent areas.The results of the research roughly agree with observation data of the actual principal earthquake and its strong aftershocks.In addition,the observation data anomalies include the anomalous information in apparent resistivity,which is directly associated with the earthquake and the data anomalies in apparent resistivity caused by certain disturbance factors.Therefore,the results have scientific significance in earthquake forecasting and obvious uncertainty;however,the testing is only tentative.Moreover,this paper examines several important factors in geo-electrical observation such as environmental protection because daily environmental disturbances have gradually restricted further development of such observation on the earth’s surface.After surveying the operational aspects of geo-electrical stations,it is determined that developments in down-hole observation configurations or remote unmanned stations may lessen environmental disturbances when environmental protection is not possible.更多还原
