摘要
在地电阻率各向异性、地磁垂直分量日变化幅度响应比和逐日比、地磁垂直分量北京时21点绝对值空间相关及地磁垂直分量日变化空间相关方法在江苏地区的研究结果基础上,综合分析了这些方法提取的江苏及周边地区中强震异常的综合特征,给出了这些异常在震前出现的先后次序、地震三要素与这些异常的综合关系。
Based on the research results on ground resistivity anisotropy degree, load-unloading response ratio and day by day ratio of daily variation amplitude of geomagnetic vertical component, spatial correlation of absolute value of geomagnetic vertical component of Beijing 21 hour and spatial correlation of daily variation of geomagnetic vertical component, we analyze the synthetical characteristics of these anomalies before the moderate strong earthquakes and gave the order of these anomalies and the synthetical correlation of these anomalies with the three ele- ments.
