地震,是人们通过感觉和仪器察觉到的地面振动。强烈的地面振动,即强烈地震,会直接或间接地给人民生命、财产带来巨大的威胁和破坏。地震虽与风雨、雷电一样,是一种极为普遍的自然现象,但其危害程度可谓群害之首。由于地震预报属世界性科学难题,至今还处于探索阶段,因此,绝大多数地震还无法作出准确的预报。鉴于这种现实,便给我们提出: Earthquakes are ground vibrations that people perceive through their senses and instruments. Strong ground vibration, that is, strong earthquakes, will directly or indirectly bring great threats and sabotage to people’s lives and property. Although the earthquake, like lightning storm and lightning storm, is an extremely common natural phenomenon, its damage can be described as first. As the earthquake prediction is a worldwide scientific problem, it is still in the exploratory stage so far, so the vast majority of earthquakes can not make accurate forecasts. Given this reality, we have put forward:
