摘要
利用常规分析方法年变曲线、矢量图曲线分析研究了山西地区MS≥4.0和国内外MS≥7.0地震前地倾斜、地应变资料所出现的短期和临震异常变化,统计了异常开始至发震时间、异常持续时间、异常结束至发震时间及异常形态等,通过对山西地倾斜、地应变资料的日均值做一阶差分分析,并对典型震例进行剖析得出了山西地区(近场)4.0级以上地震和远场7.0级强地震前地倾斜、地应变的短期、临震异常特征。
Based on the regulations of ＂the Appraisal Standard for Great Earthquake Rapid Report made by National Seismic Stations＂ , implemented on Jan. 1, 2009, the main problems in rapid report of Taiyuan Reference Seismological Station in 2009 are summarized and analyzed. Some measures for improving the quality of earthquake rapid reports are put forward.
