【摘要】 华北地区历史地震频繁,2000年以来出现地震平静现象,为了更好地对这一现象进行分析,我们利用基于地震周期谱分析的线性合成概率预测方法,针对晋冀蒙交界地区、冀鲁豫交界地区、唐山老震区、阴山燕山地震带进行研究。研究结果表明,这一方法对这些地区的地震活动有一定的预测能力,并给出了R值评分检验效果。更多还原

【Abstract】 Strong earthquakes occurred frequently in North China area in history,but it showed tranquil since 2000.In order to analyze this phenomenon,we studied the joint area of Shanxi,Hebei and Inner Mongolia,the joint area of Hebei,Shandong and Henan province,Tangshan earthquake region, Yinshan Mountain and Yanshan Mountain earthquake belt with linear probability method that based on spectral analysis of earthquake.The results show that the method has prediction ability in some extent,and the ability is tested with R-value.更多还原
