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。
This paper introduces the research and prediction of earthquake conditions before and after the MS6.6 MS6.6 earthquake in Zhang County, Min County, Gansu Province on July 22, 2013, and evaluates the earth resistance appeared in the southeast and nearby stations in the vicinity of the epicenter Abnormal observation data. It is considered that: (1) The two predicted earthquakes proposed in the immediate and immediate earthquakes are in line with the actual conditions of the main and aftershocks of the earthquake; (2) the data anomalies include the earthquakes And the anomalous interference data due to the changes of station observation environment, there are some scientific significance and enlightenment in the prediction of the earthquake conditions after the earthquake before the earthquake, and there are also obvious uncertainties. Finally, it emphasizes the importance of intensifying the protection of the geoelectric environment.
