Isn't there an earthquake in the earthquake zone? It is possible to move people in the earthquake zone to a safe place. Why is it not easy?

1 No. It seems that you need to know the type of earthquake first. Please watch carefully.

Earthquakes can be divided into tectonic earthquakes, volcanic earthquakes and impact earthquakes.

Tectonic earthquakes are caused by structural changes, especially fault activities, and most earthquakes in the world are tectonic earthquakes. Earthquakes in this area are difficult to predict.

Volcanic earthquake is an earthquake caused by volcanic eruption, including tectonic earthquake caused by volcanic activity. The range of this kind of earthquake is not large, generally within 10km, so it is necessary to prepare for the prevention after large volcanic activity.

Impact earthquake is caused by violent vibration such as landslide or collapse, or karst cave collapses due to long-term groundwater erosion in carbonate rock areas, so it is called collapse earthquake. This is still difficult to predict.

In addition to the above reasons, it depends on the magnitude of the earthquake, which will spread far away.

In addition, if you emigrate, people in Wenchuan, Beichuan and Qingchuan earthquake areas should emigrate. Ai Nanshan, director of the Institute of Environmental Science and Engineering of Sichuan University and a geoscientist, said: "The population load in the Longmenshan earthquake area is already excessive, and now we should do subtraction instead of addition." But where to move? "Not too far from Wenchuan, the immigrants in the Three Gorges reservoir area have spent more than ten years, and hundreds of thousands of people have been stranded in more than half of China. Even densely populated areas like Shanghai have accepted the resettlement task. It's really supersaturated
