An earthquake of magnitude 3.8 occurred in Eryuan County, Dali Prefecture, Yunnan Province. Is an earthquake of this magnitude destructive?

At about 6: 00 p.m. on March 1 Sunday 13, an earthquake of magnitude 3.8 occurred in Eryuan County, Dali Prefecture, Yunnan Province. According to the China Seismological Network, the epicenter of the earthquake was located at 100 degrees east longitude and 26 degrees north latitude, with a focal depth of 10 km. Generally speaking, an earthquake of magnitude 3.8 is not destructive, and people who don't pay attention may not notice it. Some people may find that the hanging clothes are slightly shaken in a quiet room, which has little effect on the whole.

An earthquake occurred in Eryuan County, Yunnan Province. According to the China Seismological Network, an earthquake of magnitude 3.8 occurred in Eryuan County, Yunnan Province on the evening of March/KLOC-0. The earthquake happened in rural areas. There are 10 villages such as Laping Village, Wenshui Village, Qisheng Village, Buddhist Temple, Laping Shao and Cao Jia within 5 kilometers around the earthquake, with an altitude of about 2538 meters. There are also many towns and villages, such as Yufeng Town, Shangguan Town, Yousuo Town and Ironmaking Township. The epicenter was 13km from Eryuan County, 5 1km from Dali City and 292km from Kunming City.

The destructive power of the earthquake is divided into 3.8. Earthquakes are usually less destructive. Because of the different environment, some people may not notice it, and some people may feel a slight swing. The magnitude of earthquakes can generally be divided into the following ways: first, weak earthquakes, generally less than magnitude 3, can not be felt at a deep source, and can be detected at a shallow source; Secondly, there are sensible earthquakes, including earthquakes of magnitude 3 to 4.5, which people can feel, but most of them will not cause any damage; Third, moderate earthquakes, including earthquakes of magnitude 4.5 to 6, have certain destructive power, but how much damage can be caused depends on how far away from the epicenter and whether the source is deep or shallow. Finally, there are strong earthquakes, including earthquakes of magnitude 6 or above. If it exceeds magnitude 8, it is called a major earthquake.

Due to the limitation of science and technology, human beings can't predict earthquakes well at present, so they can only plan ahead and prevent earthquakes. First of all, we should understand and master the methods of self-protection and self-rescue in the event of an earthquake, and prepare an earthquake-proof bag at home, which contains first-aid medicine, a certain amount of food and water. Take time to teach children the knowledge of preventing earthquakes and other disasters, and exercise with them appropriately; Look at the weather forecast and predict the natural disasters that the community may face. Once receiving the earthquake alarm from the relevant departments, immediately turn off the power switch and liquefied gas, and quickly evacuate to the open area with necessary products; Once it is too late to evacuate, you should give priority to hiding in corners, under tables and other places that can protect yourself. The closer you are to the food and water in the house, the better. If possible, cover your nose and mouth with a wet towel.
