Extended information:

Earthquake disaster prevention and mitigation are the main solutions to prevent and reduce earthquake disasters. It is a building designed to improve earthquake resistance. The main contents of earthquake prevention and disaster reduction include earthquake prevention and disaster reduction planning, earthquake monitoring and forecasting, earthquake disaster prevention, earthquake emergency rescue, post-earthquake transitional resettlement and recovery and reconstruction, as well as supervision and management, legal liability, etc.

Occurrence background:

Earthquake, commonly known as earthquake, is a common natural phenomenon like ordinary wind and rain, and is a manifestation of the movement of the earth's crust, that is, the interior of the earth. Vibrations on the earth's surface caused by the sudden release of slowly accumulated energy.

According to statistics, about 5 million earthquakes occur around the world every year. Most of them are small and cannot be detected without sensitive instruments. , accounting for about 99% of the total number of earthquakes, and the remaining 1% will only be felt by people about 50,000 times.

Under normal circumstances, earthquakes with a magnitude of 5 or above can cause damage, and are customarily called earthquakes. Destructive earthquakes occur on average about 1,000 times a year; strong earthquakes of magnitude 7 or above occur on average 18 times a year; major earthquakes of magnitude 8 or above occur 1-2 times a year.

The earth is in constant motion. , the movement of the earth generates many forces, the most important of which is the force generated by the movement of the crust.

During the movement of the crust, the underground rock layers will be squeezed, stretched, and twisted to varying degrees. When the force reaches a certain level, a sudden and rapid rupture will occur at a weak point in the rock structure or at the original fault. The place where the rock layer breaks is the earthquake source, and the vibration generated by the rock layer break is Earthquakes.

90% of earthquakes on the earth are caused by fractures in the earth's crust. These earthquakes are called tectonic earthquakes. In addition, volcanic eruptions can cause volcanic earthquakes; cave collapse can cause collapse earthquakes. /p>

Reservoir water storage can cause reservoir earthquakes; artificial blasting can also cause artificial blasting earthquakes. Since these types of earthquakes are small in number and energy, the degree of damage caused is also small. Therefore, what we need to prevent is mainly structural Earthquake.
