A sudden earthquake occurred in Dali. Were there any casualties in the accident?

According to news after the earthquake, there were no casualties. The epicenter of the Dali earthquake was located at 100.30 degrees east longitude and 25.59 degrees north latitude. It was roughly located near Fengyi Town in the east of Dali City. The earthquake magnitude was 2.8 and the focal depth was 8 kilometers. The magnitude of this earthquake was low and a slight tremor was felt. 1. The focal depth of the earthquake is 8 kilometers.

Speaking of the focal depth of 8 kilometers, let’s first understand what the focal depth is. The place where the earthquake occurs is called the earthquake source. This should be easy to understand. Then draw a vertical line upward from the earthquake source position. The point that intersects with the ground is called the epicenter. The distance between the earthquake source point and the epicenter is called the focal depth. If the distance between the earthquake source point and the epicenter The distance is 8 kilometers, then we say that the focal depth of this earthquake is 8 kilometers.

The following is the explanation given by the encyclopedia, you can refer to it:

The focal depth refers to the place where the seismic wave originates, called the hypocenter (also called Focus). The vertical projection of the earthquake source on the ground. The point on the ground closest to the earthquake source is called the epicenter. It is the earliest part to receive vibration. The depth from the epicenter to the source is called the focal depth. Focal depth is one of the factors that affects the size of earthquake disasters. 2. How to deal with an earthquake?

Our country is an earthquake-prone country. Since the 20th century, more than 800 earthquakes of magnitude 6 or above have occurred. Since the 20th century, more than 500,000 people have died in earthquakes in our country, accounting for approximately 10% of the world's earthquake deaths during the same period. half the number. Earthquakes are likely to occur when crustal movements occur frequently, and earthquakes are extremely destructive.

1. Bungalow escape

If a devastating earthquake occurs suddenly, the average time given to us is only about 12 seconds, so it is also called the golden 12 seconds of self-rescue. If you encounter an earthquake, be sure not to panic, be more calm, and immediately choose a safe place to take shelter. If you live in a bungalow, put a soft object such as a school bag on your head, and then quickly go to an open place and squat in an open square. Or lie down and protect your head and neck. Be sure to remember to stay away from trees, rivers, and high-voltage lines.

2. Building Escape

It is unscientific to say that the higher the floor, the more unsafe it is during an earthquake. Nowadays, high-rise buildings are generally fully reinforced concrete frame structures, which are often more dangerous than bungalows and bungalows. The short buildings are solid. Do not jump out of windows or take elevators during an earthquake. If the shaking is severe, seek shelter in a safe place indoors to ensure your own safety. Quickly hide under sturdy furniture, or in a room with a load-bearing wall and a small space, such as a bathroom or kitchen, but be careful not to hide near the outer walls of the room. Then cover your head with whatever you can find around you, and wait until the earthquake subsides a little before escaping outside.

3. Self-rescue if trapped

If you do not escape in time and are unfortunately trapped in the ruins, you must stay calm and see if you can break free. Cover your mouth and nose to avoid inhalation. Dust, if you can't break free, forget it, don't cry, save your strength, pay attention to what's going on outside, don't yell blindly, use your mobile phone or hit rocks to send out a distress signal, and wait for rescue. If there is food around, be sure to control the amount you eat because you never know how long you will be trapped.

4. While driving

If you are driving during an earthquake, it is best to pull over immediately, get out of the car, and run to an open area while ensuring safety. It is easy to be injured by falling objects on the roadside in the car. If you are in a bus or bus, hold on to the handrails, lower your center of gravity, and hide near the seat.

5. When traveling

If you encounter an earthquake while traveling, you must follow the instructions of the scenic area personnel, evacuate in an orderly manner, and stay away from mountains, rivers, and high-rise buildings with particularly large amounts of glass as soon as possible.

6. After the earthquake

Do not relax your vigilance even after the earthquake. There are often aftershocks after a major earthquake. Do not return home to retrieve your belongings before you are sure whether it is safe. Major disasters are followed by major epidemics, and earthquakes often cause water pollution. Therefore, you must pay attention to drinking water safety after an earthquake. Try to drink boiled water, not raw water, and never eat food that has been soaked in water. It is also necessary to cooperate with professionals to eliminate flies, mosquitoes, rats and other tasks.

In short, earthquakes are something that none of us want to encounter, but when we encounter an earthquake, we must deal with it calmly, strive to survive, and wait for rescue. Earthquakes are inevitable, but as long as we take scientific and reasonable self-rescue methods, we can minimize the damage caused by disasters.
