Spherical pattern of tide-isostasy model and its application

In this paper, a calculation formula on spherical pattern of tide-isostasy model is established. The calculation indicated that for the oceanic crust plate which central angle is over 90°, a huge value(its equivalence is 108 N)of accumulative force moment in the crustal isostatic movement caused by tide can trigger off relative motion of plate, resulting in earthquake and volcanic eruption. The seismic wave features during the year 2001-2004 is an obvious example. The paracycles, i.e. 4, 12, 60, 36, 243, 372 and 396 years of tidal fluctuation can provide an explanation for some respective natural disasters. For example, La Madre paracycle about 60 years corresponds to the global disasters,earthquake and typhoon disasters.

海平面震荡与地震的关系研究

潮汐—均衡模式球面模型的计算表明,对于圆心角>90°的海洋地壳板块,潮汐变化产生的地壳均衡运动累加力矩数值巨大,等效应力为108 N,足以形成板块相对运动,诱发地震活动和火山喷发。本文收集了大量证据,表明强潮汐与地震的相关关系,并据此预测2005年将发生拉尼娜事件。
