地震就像刮风下雨一样,是一种普遍的自然现象,但它却具有很大的危害性。为了减少地震的损失,青少年、儿童及其父母,必须对地震的有关知识有所了解,并掌握必要的、正确的应急措施。地震是有前兆的,总结这些前兆的分布和变化规律,地震是可以预报的。所谓地震前兆是指地震发生前一段时间内出现的各种异常情况,其中有我们能够直接感觉或观测到的异常情况,如水井里的水突然变浑、变味、冒泡,大幅度的水位涨落,动物异常:犬狂吠,蛇出洞,冬眠的蛇也会出来,老鼠成群并表现惊呆,家畜家禽出现 Earthquakes, like windy rains, are a common natural phenomenon, but they are very dangerous. In order to reduce the loss of earthquakes, young people, children and their parents must understand the relevant knowledge of earthquakes and have the necessary and correct emergency measures in place. Earthquakes are precursors. Summarizing the distribution and variation of these precursors, earthquakes can be predicted. The so-called earthquake precursors refers to a variety of anomalies that occur within a period of time before the earthquake. Among them are the anomalies that we can directly sense or observe, such as sudden muddy water in the wells, odors and bubbles, drastic water level rises Animal anomalies: dogs bark, snake holes, hibernating snakes will come out, rats in groups and show shock, livestock poultry appear
