Which floor of a traditional building is the safest in an earthquake?

Some people say it is a low floor. The reason given is that it is easy to escape because the floor is low. Is that true? (In a real earthquake, you may be sleeping, or the earthquake makes people "drunk" and can't run.) The answer is, of course, wrong! The above figure below shows that when the Taiwan Hualian earthquake occurred, the strong earthquake caused the damage to the columns on the first and second floors of the hotel near the park road. The building collapsed instantly, and the third floor became the first floor. The tenants on the fifth floor were stunned.

What is a super earthquake

Tangshan earthquake, Wenchuan earthquake, Yushu earthquake, Ya'an earthquake and other well-known earthquakes in China are all over fortified earthquakes. Take Wenchuan as an example: Before the Wenchuan earthquake, the fortification was 7 degrees equivalent to a magnitude 5 earthquake at the epicenter, while a magnitude 8 earthquake with a destructive degree of 11 degrees occurred. Each magnitude difference is about 31.6 times, which means that the earthquake energy level acting on Wenchuan is more than 30000 times that of our fortification!

What is an earthquake - Characteristics of earthquakes in China

Earthquake is a natural phenomenon in which the rapid release of energy from the Earth's crust causes vibrations and generates seismic waves. The mutual compression and collision between plates on Earth, causing displacement and rupture of plate edges and interiors, is the main cause of ground vibrations (i.e. earthquakes).

Explanation of key terms related to earthquakes

The three concepts of magnitude, intensity, and seismic fortification intensity (fortification standards) are easily confused by many people.
