In normal times, we can predict earthquakes through some abnormal situations. Before the earthquake comes, the groundwater level will suddenly rise. If we live in the country, we can observe the water level in the well. If the water level in the well at home suddenly rises or pops up, it is likely to be a precursor to the earthquake. In this case, we must evacuate quickly and never stay where we are.
Before the earthquake, the animals in the zoo will be crazy and uneasy. Some animals are docile and even aggressive. Some animals look depressed, eat or drink water, and even whine. Under such circumstances, the relevant staff of the zoo should also feed back such abnormal behavior to the public to let the public know about the situation.
At school, we all learned some knowledge about earthquake prevention. Before the earthquake, cold-blooded animals such as frogs and snakes will suddenly migrate in large numbers. They are not afraid of people and run on the road directly. We can also observe the types of clouds to judge whether an earthquake will happen. If the clouds on that day are particularly low and shaped like fish scales or waves, they are called earthquake clouds. Once they see this situation, they should flee quickly.
Generally speaking, before an earthquake, there will be many things to give us early warning. After discovering such a situation, you must inform everyone as soon as possible and quickly move to an open place. Never stay in a densely populated place.
