摘要
应用川滇 1 1个地震带 (区 )资料 ,研究了与地震频度 N或地震能量 E有关的各种地震学指标在描述地震活动性变化方面的相关性 .统计相关检验表明 ,从地震频度 N或地震能量E变换得到的各种地震学指标 ,与 N或 E在描述地震活动性变化方面都在一定程度上相关 .凡属线性变换的 ,相关系数为 1 ;偏离线性变换愈小 ,相关系数愈大 .
Correlation among various seismological prediction indexes related to earthquake frequency N or energy E for describing seismicity changes is studied by seismic data of 11 seismic zones (areas) in the Sichuan Yunnan region. A statistical test for correlativity shows that seismicity indexes obtained from transformation of earthquake frequency N or energy E have correlation to a certain extent while they are used to describe seismicity changes. If the transformation is linear in all cases, the correlation coefficient is equal to 1. The smaller the transformation deviation from linearity, the bigger the correlation coefficient is.
