1303年山西洪洞8级大地震有关问题的讨论
|
摘要
用"垂震底继"的准则讨论了1303年和1695年山西2次大地震的关系。指出1303年山西洪洞8级大地震与华北其他8级大震的时间间隔多为25a的倍数。讨论了1303年大震发生的构造条件是块体交界和近于35°纬带。讨论了共轭断层轮换发震观点的困难性。
From the regularity of "occurrence of earthquake on bottom fault following the occurrence of earthquake on perpendicular fault", the relation between the 1303 Hongtong ,Shanxi, strong earthquake and 1695 Linfen ,Shanxi, strong earthquake is discussed. It is pointed out that the majority of temporal intervals between the 1303 strong earthquake and other large earthquakes in the North China are multiple of 25 years. The geodynamic and tectonic conditions on occurrence of the 1303 large earthquake are edge of the stable ordos block and near to the 35° latitude belt. Finally, the difficulties of alternately occurring earthquake along conjugate faults are also pointed out.
