How to turn on the earthquake early warning function of mobile phone, and what is its principle? How to avoid danger after receiving earthquake warning?

To turn on the earthquake warning function of the mobile phone, you can follow the following steps:

1. Open the phone settings and find the option of "earthquake warning" or similar name.

2. After entering this option, enable the earthquake early warning function.

The principle of mobile phone earthquake early warning function is based on earthquake monitoring network and earthquake early warning system. When an earthquake occurs, the earthquake monitoring station will monitor the seismic waves and send relevant information to the earthquake early warning system. The earthquake early warning system will analyze the seismic wave information, predict the time and place of the earthquake according to the propagation speed of the seismic wave and the distance from the earthquake center, and send the earthquake early warning information through radio, Internet and other means. The earthquake warning function of mobile phone can receive these earthquake warning information, and remind users through sound and vibration, so that they can take preventive measures before the earthquake comes.

After receiving the earthquake warning, you can take the following measures to avoid risks:

1. If you are indoors, quickly hide under a solid table, bed or wall to protect your head.

2. Stay away from large furniture, glass windows, external walls and other objects that may cause harm.

3. Try to avoid using the elevator.

4. If you are outdoors, try to stay away from buildings, telephone poles, trees and other objects that may collapse, and quickly find open areas.

5. Try to stay calm, listen to the command of the civil defense department and the earthquake warning information, and wait until the earthquake is over.

The above are general risk-avoidance suggestions, and the specific risk-avoidance measures need to be decided according to the specific conditions of the earthquake and the surrounding environment. If there are frequent earthquakes in your area, it is recommended to know the relevant earthquake emergency knowledge in advance and make preparations according to the local earthquake emergency plan.
