How do I turn on the earthquake warning function on my phone?

After the earthquake, the China Earthquake Early Warning Network automatically produced early warning information as soon as possible, and the WeChat mini-program "China Earthquake Network" pushed the early warning information service to 251692 users in the surrounding area.

Remind everyone that earthquake early warning is not an earthquake prediction, but a scientific and technological defense line that "races" against seismic waves. As shown below, turn on the earthquake warning function to receive official and authoritative earthquake early warning information conveniently and quickly.

Why don't people see the warning?

Why can't some Beijing citizens receive early warning notices when there is an earthquake nearby? In this regard, the WeChat Mini Program explained that the failure to receive the earthquake warning notice may be the following four situations:

First, the magnitude of the earthquake did not meet the push conditions. The Earthquake Network Mini Program is pushed according to the national ≥ magnitude 4 earthquake, and the WeChat Mini Program of each province will set different release conditions according to the actual situation of the province and the impact of the far-field earthquake.

Second, the estimated intensity of the area of concern did not reach the reminder threshold. At present, the earthquake early warning WeChat applet gives a strong reminder for the area with an estimated intensity of ≥2 degrees (Android users can receive a screen notification), and the intensity ≥ 0 degree area is reminded by WeChat message notification, and the intensity < 0 degree area does not prompt.

Third, there is the problem of mobile phone settings. If you have not completed the WeChat notification setting, please follow the following steps to troubleshoot: 2. Open the phone settings - Notifications - Allow WeChat notification permission (allow the lock screen to receive notifications). 0. The first time you receive earthquake warning information, the default is the rejection state, you need to click "Resume receiving earthquake warning notification" in the upper right corner.

Fourth, the mobile phone is not connected to the Internet. No network on your phone: Turn on your phone's Wi-Fi or cellular network.
