| 摘 要： | 在强震活动轮回和期幕划分等研究中,强震事件的样本数量往往影响并限制了信度和结果外推,特别是强震活动较弱时期对状态的判断将出现较大的不确定性. 强震孕育过程中的中小地震活动状态实际上反映了强震活动的规律性. 本文采用基于Weibull分布的中小地震信息熵对中国大陆西部的强震活动状态进行分析. 结果显示,西部地区目前处在低...

| Abstract: | In the study of strong earthquake cycling and periodicity,the sample size of strong events often influence and even limit the reliability and result extrapolation,especially when strong earthquake activity is low,there will be large uncertainty in state judgement.Small-moderate earthquake activity in the seismogenic process of strong earthquakes actually reflects the characteristics of strong earthquake activity.In this article,we analyse the state of strong earthquake activity based on seismic information ... |
