每当自然灾害发生的时候，总会伴随出现一些征兆，只要平常观察仔细，就能躲避一些灾难，在这里给大家分享一下地震的前兆有哪些。

步骤/方法
最好在家里醒目一点的位置上放一个指南针，一般地震前半分钟内，指南针会出现指针乱动的现象，而且家里的其他电器也会出现用![](https://wkrtcs.bdimg.com/rtcs/image?w=500&md5sum=54b952347f7e20556598e06338cfea64&sign=c8d49a047a&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=32&ipr={"t":"img","w":"500","h":"375","dataType":"jpeg","c":"word/media/image2.png","imgOriW":500,"imgOriH":375})
电不稳定，比如电灯一闪一闪，音响一颤一颤的。
看周边的动物是不是有异常，一般地震之前附近的猫狗猪之类的动物都会到处乱跑，水池或者河里的鱼会不断的跳出水面，翻白肚，地里会有很多老鼠跑出来。

家里的井水会不断地冒泡，往上涌，水位变化明显，还会变得更加浑浊，甚至可能会出现井水变浅见底的现象。

一般三级以上的地震开始之前都会有一些震动的声音从地底传上来，如果地震越大声音就越沉厚，地震越小的话声音就越尖锐，有点像是那种大石头滚动的声音。

地震之前地表还有可能会冒出一些雾气来，一般是没有颜色或者浅白色的，和平常的雾差不多，有时可能会带一点奇怪的味道，有些地方地震前几十秒内可能还会出现地表发光的现象，不过这个相对少见一些。

注意事项
一般预感有地震立刻往外面宽敞的地方跑。
