First, don't worry when there is a big earthquake. Destructive earthquake takes only 12 seconds on average from when people feel the vibration to when buildings are destroyed. In this short time, you should make a quick choice according to your environment to ensure safety. If you live in a bungalow, you can run to the door quickly. If you live in a building, don't jump off a building. You should immediately cut off the switch and gas, take refuge in places with small spans such as toilets, or under tables and beds, and evacuate quickly after the earthquake to prevent strong aftershocks.

Second, there are many people who need to find a hiding place first. Schools, shops, theaters and other places where people gather should avoid panic if they encounter an earthquake. After the earthquake, they should immediately hide under tables, chairs or solid objects and evacuate in an orderly manner.

Third, stay away from the danger zone. If you encounter an earthquake in the street, cover your head with your hands and quickly get away from the building and go to the center of the street. If you encounter an earthquake in the suburbs, you should pay attention to stay away from cliffs, steep slopes, river banks and high-voltage lines. Moving cars and trains should stop at once.

Fourth, buried to preserve physical strength. If you are unfortunately buried under the rubble after the earthquake, try to stay calm and try to save yourself. When you can't get out of danger, you should save your strength, try your best to find water and food, create living conditions, and wait patiently for help.

5. Keep your mobile phone and enough batteries at your side.
