【摘要】 结合地震地质构造,利用地震学有关方法,运用各向异性度对新沂台视电阻率进行分析;运用滑动平均对新沂台短水准进行分析;运用加卸载响应比对地磁Z分量进行分析。结果表明:在黄海5.1级地震前,存在中短期异常,但临震异常不明显。更多还原

【Abstract】 Based upon seismological geology tectonic, some relevant methods of seismology are applied in the paper. The anisotropy of resistivity is analyzed in Xinyi station. At same time, the short leveling is analyzed by the running mean method and the Z component of geomagnetism is also analyzed by the load-unload response ratio. It is revealed that there were obvious mid-short anomalies before Huanghai MS 5.1earthquake at Xinyi station; however, the impending earthqua- ke anomalies weren’t obvious.更多还原
