How many earthquakes can the high-rise residential buildings under construction in Tangshan withstand? After the earthquake, everyone was afraid to live in the building. Can Tangshan build tall buildings? You can build high-rise buildings. Since the Tangshan earthquake, the Ministry of Construction has stipulated that the seismic requirements of all houses (including civil buildings) should not be lower than Grade 8 (intensity).

In addition, it should be noted that strength and magnitude are two concepts, which are very different.

Magnitude is the energy released by the source, which is divided into 1 ~ 9. The highest level is 9.9, and strength refers to the impact on the ground and the degree of damage at a destination. It is directly related to the magnitude, the distance from the source to the ground and the distance from the epicenter. The deeper the source, the smaller the impact on the ground, and the farther the distance, the smaller the impact.

Precautions:

Don't worry when there is a big earthquake. Destructive earthquake takes only 12 seconds on average from when people feel the vibration to when buildings are destroyed. In this short time, you should make a quick choice according to your environment to ensure safety.

If you live in a bungalow, you can run to the door quickly. If you live in a building, don't jump off a building. You should immediately cut off the switch and gas, take refuge in the bathroom or under the table and bed for a while, and evacuate quickly after the earthquake to prevent strong aftershocks.

Stay away from dangerous areas. If you encounter an earthquake in the street, cover your head with your hands and quickly get away from the building and go to the center of the street. If you encounter an earthquake in the suburbs, you should pay attention to stay away from cliffs, steep slopes, river banks and high-voltage lines. Moving cars and trains should stop at once.
