灾害频发和地磁减弱的关系
|
摘要
近年来全球强震频发,其灾难发生的原因可能是由地磁减弱引起的。研究表明,地磁减弱的原因在于两极冰盖融化导致地壳和地幔转动惯量增大及自转减慢,由此引发核幔差异旋转在数值和方向上的改变。在磁场减弱和磁极反向过程中,太阳辐射的增强和核幔热能的释放与灾害有一一对应关系。这一研究结论与美国学者最近发现的"浅核磁场"相一致。全球变暖与地磁减弱的相关性表明,气候变暖不仅会导致海平面上升,而且会导致频繁的地震、火山活动。
Recently,global earthquakes occur frequently,which may be caused by geomagnetic weakening. The study showed that the reasons of geomagnetic weakening were the increase of crust-mantle rotatioanal inertia and the reduction of earth rotation led by polar ices melting,which caused the change of core-mantle differential rotation on numerical value and direction.During the process of geomagnetic weakening and polarity reversal,the increase of solar radiation and the release of core-mantle thermal energy were in one-to-one correspondence with disasters. This conclusion was consistent to the " shallow core field" discovered by American scholars.The correlation of global warming to geomagnetic weakening showed that climate wanning not only caused sea level rise,but also led to frequent earthquakes and volcanic activities.
