摘要
为研究太阳活动与全球大震的关系,引入一个无量纲的"地震能量函数√G",并分析研究了1681—2011故年间全球M≥7.0大震的能量释放的时间序列.由此发现全球大震在太阳活动周4个阶段的分布和活动度,随震级的强度而异.提出地壳对太阳风暴加卸载响应模式,用于解释此现象:通过考察最近331a,得出全球共发生了10个M≥9.0超级巨震的时空分布特征,特别是太阳活动峰年期间没有发生过超级巨震.该研究结果可为判断全球大震提供参考.
The relationship between solar activity and earthquake in the world was studied by applying a dimensionless function of seismic energy √G to investigate the energy release time series of global large earthquakes （M ≥7.0）occurred during the year of 1 681-201 1.From the study,we find that the distribution and activity of global large earthquake in 4 phases of solar cycle varied with magnitude.We suggest that it can be explained by a model of load-unload response of the earth crustal move-ment to solar storm.The findings of spatial and temporal distribution characteristics of 10 M ≥9.0 super earthquakes in past years of 331 in the world and absence of super earthquake in solar maximum.The results are helpful to predict occurrence of fu-ture global large earthquake as reference.
