摘要
地震不是随机发生的,在地震发生之前,震源区存在介质弹性减弱、密度减小、体积膨胀的孕震过程,它将引起各种地球物理方法的前兆观测手段出现形形色色的变化。只要坚持实践—研究—再实践,反复不断地加深规律认识,不断地积累探索,就能循着渐进式预测之路,逐渐实现地震预测。
Earthquake occurrence is not at random. Before earthquake,the elasticity and density of the medium in source region would decrease and the volume of the medium would increase.Such seismogenic process would cause various precursor phenomena changes which can be observed by many geophysical observation methods. As long as we persist in the process of recognition of practice-research-practice, the experience and knowledge for earthquake prediction can be accumulated gradually and earthquake prediction will become true step by step.
