WeChat is a blockbuster social software launched by Tencent in January 2011. After more than a decade of development, this cross-system, cross-operator application has more than 1.3 billion monthly active users. WeChat moments and group chats allow us to share interesting things in life with friends and play games together; Official accounts and video accounts can provide articles, videos and other content; WeChat sports can play PK with friends together and compete; The care model is vividly demonstrated in caring for the elderly, and the emergence of mini programs allows us to enjoy services such as life services, financial management, transportation, shopping and consumption. Obviously, WeChat, an all-round mobile platform, has become a way of life!
WeChat and QQ are indispensable social software in daily life. We know that since 2009, May 12 has been the National Disaster Prevention and Mitigation Day, which was established to commemorate the May 12 Wenchuan earthquake.
Yesterday, Tencent officially announced that on the 16th National Disaster Prevention and Mitigation Day (the 16th anniversary of the Wenchuan earthquake), the earthquake early warning function will be logged in on WeChat, QQ and other social software! It is worth knowing for each of us.
||Earthquake early warning
Earthquake early warning generally refers to the use of "electromagnetic waves" to send out evacuation warning information before "seismic waves" after a destructive earthquake occurs, so as to reduce the disaster loss in the early warning area.
Earthquake early warning focuses on the word early warning. The propagation speed of an earthquake is several kilometers per second, during which longitudinal waves and transverse waves are generated, the longitudinal waves propagate fast and the destructive force is small, and the transverse waves propagate slowly and have a large destructive force. When the longitudinal wave is detected, the seismic monitoring department pushes the location of the epicenter, magnitude and other information to the relevant users in the form of the fastest electromagnetic wave.
Therefore, before the destructive transverse wave arrives, it buys a few seconds for the relevant personnel, but don't underestimate this short few seconds. The data shows that 3 seconds in advance of the warning can reduce casualties by 14%, and 20 seconds can reduce casualties by 63%.
||Tencent Earthquake Early Warning Principles & Risk Avoidance Tips
Regarding WeChat and QQ earthquake warnings, many people will question the real-time nature of notifications, such as my mobile phone is turned off at night, the network is disconnected, and the message push is delayed.
In fact, according to the official introduction, WeChat has set up an independent message channel that can be flexibly expanded for earthquake early warning, and QQ already has the technical reserve of high-concurrency message push. Therefore, when the early warning information is pushed to WeChat and QQ, it can achieve second-level regional earthquake coverage.
Since our country is located in the Pacific Rim Seismic Zone and the Eurasian Seismic Zone, the earth's crust is frequently active, so it is very necessary to understand the earthquake knowledge, and grasp the golden 12 seconds of the earthquake can save lives. According to the tutorial released by the China Earthquake Network Center:
1. Keep calm, take corresponding measures according to our own position, turn off the open flame and power supply as soon as possible indoors, and look for a safe place with a small bay, load-bearing wall and water source.
2. If you are unfortunately buried, do not continue to shout for help in a loud voice, save your physical strength, and knock the water or heating pipes around you to wait for rescue.
3. Stay away from tall buildings outdoors, squat down in an open area, and follow instructions if there are staff.
4. If you are driving on the road, do not brake urgently to avoid car accidents, you need to slow down and pull over to evacuate the people in the car, and avoid open areas in an orderly manner.
5. Wild earthquakes may cause secondary disasters such as rockfalls, landslides, debris flows, and tsunamis, so leave river valleys, valleys, mountains, and seashores as soon as possible.
6. Bring as few personal belongings as possible.

||How to turn on the earthquake warning function of WeChat and QQ
At present, the earthquake early warning function of WeChat and QQ supports Sichuan Province, and the national WeChat earthquake early warning service platform has entered the internal testing stage. I believe that I will "meet" with you soon.
1. Open the WeChat App, enter the search interface, the Apple phone is at the top of the WeChat interface, and the Android phone clicks the magnifying glass icon in the upper right corner of the WeChat interface;
2. Search for the official account of "Sichuan Earthquake Observatory", and pay attention to the official account to open the earthquake early warning;
3. Open the applet to set the warning location - > click to agree to privacy protection - > click to turn on the earthquake warning - > click to allow the warning notification - > click to allow location authorization.
1. Open the QQ software and click "Search" at the top of the interface.
2. Enter "QQ City-wide Assistance" - > click "Earthquake Warning" - > click Add Warning Location - > select the intensity range.

All in all, Xiaobian believes that the earthquake early warning function of WeChat and QQ is a more practical function. Xiaobian hopes that the earthquake early warning function will be opened in the whole country as soon as possible. At the end of the article, if you have any good suggestions, please leave a message in the comment area, and we will grow and progress together.
For more core technologies, please pay attention to Liangchen Technology, readers and friends, goodbye!
