The earthquake in the hotel

It was destroyed because it was built on an active fault.

Faults are formed by the strong pressure and tension generated in the crustal movement, which exceeds the strength of the rock layer itself and destroys the rock. Spring lakes usually develop along fault planes. It is not suitable to build large-scale projects such as dams at faults, and it is easy to induce geological disasters such as landslides.

Earthquakes are the result of material movement inside the earth. This movement is reflected in the crust, which breaks the crust and promotes the generation, development and activity of faults. "If there is an earthquake, there must be a fault, and if there is a fault, there must be an earthquake." Fault activity induces earthquakes, and earthquakes promote the formation and development of faults, so earthquakes are closely related to faults.

Extended data

Disaster losses caused by the earthquake:

1, direct disaster loss

Direct earthquake disaster is the main phenomenon of earthquake, such as earthquake fault dislocation and ground vibration caused by seismic waves. It mainly includes: the destruction of the ground, the destruction of buildings and structures, the destruction of natural objects such as mountains (such as landslides and mudslides). ), tsunami, ground light burns, etc.

2. Secondary disasters

Earthquake secondary disasters are disasters caused by direct disasters that destroy the original balance or stability of nature or society. Mainly: fire, flood, toxic gas leakage, plague and so on. Among them, fire is the most common and serious secondary disaster.

3. Fault stratification

The damage degree of earthquake disaster is not only related to the magnitude, but also related to the focal depth, the distance from the epicenter, the geological conditions in the epicenter area, the seismic performance of buildings, people's awareness of earthquake prevention, emergency measures and the degree of prediction and prevention.
