摘要

选取合肥地震台1995—2007年地电阻率观测资料,分析原始月均值曲线和归一化月速率曲线,结合安徽省及邻近地区近12年来发生的5次中强地震,探讨分析其对应关系。结果表明,地震前兆特征明显,可为今后邻近地区的中强地震提供短期预报依据。
The background variation of the earth resistivity observed at Hefei Seismic Station is analyzed. The reference values of the normal variation are obtained,which are used to confirm and extracting anomalies.The earth resistivity observation data from 1995 to 2007 at Hefei Seismic Station are processed and analyzed with the original monthly mean curve and the normalized monthly rate curve.The corresponding relationship between abnormal information and five moderately strong earthquakes happened in Anhui Province and its neighboring regions in latest 12 years is discussed.The result shows that the characteristics of earthquake precursors were quite clear before earthquakes,and it would be a relative quantitative index for earthquake prediction in neighboring areas.
