An earthquake of magnitude 3.0 occurred in Zhangbei County, Zhangjiakou City, Hebei Province. What should I do in case of an earthquake?

China is a country with frequent earthquakes. Since the 20th century, there have been more than 800 earthquakes of magnitude 6 or above. Since the 20th century, more than 500,000 people have died in earthquakes in China, accounting for about half of the world's earthquake deaths in the same period. Earthquakes may occur when the earth's crust moves frequently, which is extremely destructive.

1. If a destructive earthquake suddenly occurs, the average time given to us is only about 12 seconds, so it is also called gold self-help 12 seconds. If you encounter an earthquake, don't panic, be more calm and choose a safe place to hide immediately. If you live in a bungalow, put a soft object like a schoolbag on your head, and then quickly walk to an empty place, squat or get down in an empty square to protect your head and neck. Remember to stay away from trees, rivers and high-voltage lines.

2. It's unscientific to say that the higher the floors where buildings avoid earthquakes, the less safe they are. Nowadays, high-rise buildings are generally reinforced concrete frame structures, which are often stronger than bungalows and low-rise buildings. In case of an earthquake, never jump out of the window or take the elevator. If the earthquake is severe, take refuge in a safe place indoors to ensure your own safety. Hide quickly under solid furniture, or in a room with a load-bearing wall and little space, such as bathroom and kitchen, but be careful not to hide next to the external wall of the room. Then cover your head with anything you can find around you, wait for the earthquake to ease a little, and escape to the outside.

If you don't escape in time and are trapped in the ruins, you must keep calm and see if you can escape. Cover your nose and mouth to avoid inhaling dust. Forget it if you can't escape. Don't cry, save your strength, pay attention to the situation outside, don't make a hullabaloo about blindly, use your mobile phone or knock on a stone to send out a distress signal and wait for rescue. If you have food around you, you must control your diet, because you never know how long you will be trapped.

If you are driving during the earthquake, you'd better pull over at once, get off the bus and run to an open place, so it's easy to be injured by falling objects on the roadside when you stay in the car. If you are on a bus or coach, grab the handrail, lower your center of gravity and hide near the seat.

5. When traveling, when encountering an earthquake, you must obey the command of the personnel in the scenic spot, evacuate in an orderly manner, and stay away from tall buildings with mountains, rivers and glass as soon as possible.

6. After the earthquake, you can't relax your vigilance. After an earthquake, there are often aftershocks. You must not go home to get your things until you are sure whether it is safe. After a major disaster, there is a major epidemic, and earthquakes often cause water pollution. Therefore, after the earthquake, we must pay attention to the safety of drinking water, try to drink boiled water, do not drink raw water, and never eat soaked food. It is also necessary to cooperate with professionals to kill flies, mosquitoes and rats.

In a word, an earthquake is something that each of us doesn't want to encounter, but when we encounter an earthquake, we must calmly deal with it, try our best to survive and wait for rescue. Earthquakes are inevitable, but as long as scientific and reasonable methods are adopted to save themselves, the loss of disasters can be minimized.
