不久前还以为引起地震的过程相当长而且相当复杂,以致无法直接观测,也不可能作出准确的地震预报。但是,近年来已经实际证实:可以根据构成地壳上层的岩石物理特性的变化预测出破坏性地下风暴的临近。地球物理学家已经查明:地球内部的巨大位移能以很微弱的、勉强可以测到的运动形式反应到地面上来,这种运动被地球物理学家称为“山舞”。在地震前几天,巨大的山体开始 It was not long ago thought that the process of causing earthquakes was quite long and complicated so that it was impossible to directly observe or make an accurate earthquake prediction. However, it has been confirmed in recent years that the approach of destructive underground storms can be predicted based on changes in the petrophysical properties of the upper crust. Geophysicists have identified that huge displacements within the Earth can be reflected on the ground in the form of very weak, barely measurable movement, which is termed “mountain dance” by geophysicists. A few days before the earthquake, a huge mountain began
