The weather in March today.

? There have been many earthquakes in Marcand, Sichuan, and netizens all said that they felt asleep in the cradle, which shows how frequent earthquakes were at that time. In my sleep, they started again soon. I can really think of that kind of anxiety, but after the earthquake, we must pay attention to rain protection to prevent geological disasters and secondary disasters.

In fact, many times there will be rainy weather after the earthquake. When an earthquake occurs, it shows that the earth's crust is violently moving, which will eventually lead to higher and higher ground temperature and rapid evaporation of water. After the underground water evaporates, it will slowly walk into the air along these gaps, forming an updraft and finally turning into rain.

After the earthquake, people are most afraid of heavy rainfall. First of all, this kind of rainfall will affect the rescue work and the accurate answer of these relief materials. The difficulty of rescue will increase and the danger will increase.

If people are trapped after the earthquake, this rainy weather is not conducive to survival, which may threaten their lives, and rain may also cause the ruins to collapse again. Coupled with the sound of rain, the rescue team may miss some faint cries for help.

If an earthquake occurs in a mountainous area, heavy rain can easily lead to geological disasters such as landslides and mudslides. Once this kind of harm happens, it will cause road congestion and rescue difficulties.

Not only that, if it rains after the earthquake, it is very easy to break out some diseases and accelerate the infection of the wound. So if it rains after the earthquake, it will cause a series of very serious effects. So after the earthquake, the most feared thing is actually rain.

However, there will be such heavy rainfall in many places after the earthquake, which may be what the old man called rainy days after the earthquake. Of course, there is no scientific basis for this statement. There are many reasons for rainfall, so it can't be directly related to the earthquake.
