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√Gto investigate the energy release time series of global large earthquakes(M ≥7.0)occurred during the year of 1681—2011.From the study,we find that the distribution and activity of global large earthquake in 4phases of solar cycle varied with magnitude.We suggest that it can be explained by a model of load-unload response of the earth crustal movement to solar storm.The findings of spatial and temporal distribution characteristics of 10 M ≥9.0super 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 future global large earthquake as reference.
