摘要
用傅氏滑动法、动态距平法、速率法、均值法等对山西大同台、代县台、临汾台的地电异常进行了分析 ,对地电阻率异常的判定、预报方法效能进行了评价 ,对不同的台站 ,从正常的变化形态中找出了突出异常的有效方法 ,从中提取出因地壳应力变化引起的地震前兆异常 ,结果表明 ,5 .0级以上地震在Δ=15 0
The geoelectric anomalies of Datong,Daixian,Linfen station of Shanxi were analyzed by Fourier moving method,the efficacy of the anomaly judgement and the prediction method of the ground resistivity was appraised,the effective method picking up anomaly from normal variation shape of different station and crustal stress was summarized.The conclusion showed that the medium-short term precursor anomaly of M>5.0 earthquake is obvious in the range of Δ=150 km.
