山东平原M5.5地震区域的地震活动性参数因子分析OA北大核心CSTPCD

Analysis of Seismic Activity Parameters in the M5.5 Earthquake Area of Pingyuan,Shandong,Using Factor Analysis Method

中文摘要英文摘要

引入因子分析方法,对平原地震区域中小震序列的16种地震活动性参数进行降维综合,发现目前综合指数W处于平静幕的最高值区.通过进一步单因子分析结果推测,平原地震区域地下介质可能发生变化,未来华北地区地震活动性有增强趋势.

This article introduces the method of factor analysis.It conducts comprehensive analyses on 16 seismic activity parameters of the small and medium-sized earthquake sequences in the Pingyuan earthquake area.The results show that the current comprehensive factor W was in the highest value range of this quiet episode.Further research of the single factors reveals that the underground medium in the Pingyuan earthquake area might have undergone some changes.In the future,seismic activity in north China may increase.
