【摘要】 选取豫鲁冀交界区17个数字化测震台站S波记录,对该区地震进行限定筛选,并对台站记录的地震波形进行严格仔细的参数测量与提取,分析地震波传播过程中S波分裂变化及与地震的关系,提取中等地震前S波分裂所表现的地球物理异常特征。更多还原

【Abstract】 This article selected the S-wave records of 17 digital seismic stations at the junction of Hebei Shandong and Henan provinces to screen the earthquake in the junction area. The seismic waveforms recorded by the stations were strictly measured and extracted, and the S-wave splitting during seismic wave propagation was analyzed and the geophysical anomalies was characterized by S-wave splitting before moderate earthquakes.更多还原
