Precautions:

1. When an earthquake happens, it is very important to keep a clear head and a calm attitude. Most earthquakes are felt or slightly damaged, so you must be calm when you encounter an earthquake.

2. Shock absorption should be firm indoors, which can cover the body (side) under the object, and it is easy to form a triangular space, a small studio, a supported place, an empty room and a safe place. The posture that the body should take is: squat or sit down, curl up as much as possible and lower the center of gravity.

3. Grab a solid object, such as a table foot. Protect your head, neck and eyes, and cover your mouth and nose. Avoid crowds, don't crowd around, and don't light open flames casually, because there may be flammable and explosive gases in the air.

If you are in the house when the earthquake happens, you should quickly choose a safe place, such as hiding under a desk, workbench or bed. In the unit building, you can choose to open a small bathroom and corner, relying on the support of water supply and drainage pipelines and gas pipelines to reduce casualties.
