On May 12, the WeChat official account of "Tencent" issued a document saying that the WeChat and QQ earthquake early warning functions were launched, and the ability to issue earthquake early warning for earthquakes of magnitude 5 or above in Sichuan Province has been realized 5-15 seconds after the earthquake.
How does it work?
WeChat platform
Search for the "Sichuan Earthquake Observatory" official account on WeChat, follow the official account to turn on the earthquake warning, 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.
QQ platform
Search and follow "QQ City Help" - click "Earthquake Warning" - click to add warning location - select the intensity range
Netizen: It's very practical, and it can be adapted to other regions quickly
It is reported that the Sichuan Earthquake Observatory has been connected to the official authoritative early warning data of the China Earthquake Early Warning Network, WeChat has set up an independent message channel that can be flexibly expanded for the earthquake early warning, and QQ has mature technical reserves for the high concurrency message push of a large number of users.
In this regard, some netizens said: "This is quite practical... In the future, we can continue to optimize, strive to ...... in advance" and "quickly adapt to other regions".
Tencent said it also has plans to launch earthquake warnings in more places. Under the guidance of the China Earthquake Administration, Tencent is developing a national WeChat earthquake early warning service platform, which has entered the internal testing stage and will soon be launched nationwide. QQ's city-wide earthquake early warning function will gradually cover more provinces.
The earthquake early warning function is very important, and in the event of an emergency, it gives us precious time to evacuate in an emergency. How to open different phone models ↓
- Huawei: Set up → security → emergency warning notifications → earthquake warnings
- Xiaomi: Mobile phone manager→ family care→ earthquake warning
- Honor: Set up → safety → emergency warning notifications → earthquake warnings
- OPPO/OnePlus/Realme: Set → Security→ Emergency SOS → Natural Disaster Alert→ Earthquake Alert
- vivo/iQOO: set → earthquake warning → enable earthquake early warning service → the weather app

Is early warning useful?
Is WeChat and QQ push fast?

Q: What is an earthquake warning?
A: The earthquake warning is based on the time difference. When an earthquake occurs, longitudinal waves and transverse waves will be generated, and the longitudinal waves are fast and destructive; Whereas, transverse waves have a slow speed and high destructive power.
When the seismic station captures the longitudinal wave signal, it will transmit the epicenter location, magnitude and other information to the early warning terminal through faster electromagnetic waves, so that it can gain emergency evacuation time for the surrounding cities in a few seconds to tens of seconds before the transverse wave arrives.
Q: Is early warning useful?
A: It works! Studies have shown that a 3-second advance warning can reduce casualties by 14% and 20 seconds in advance by 63%. (Source: Northwest Seismological Journal 2002 Research Report)
In just a few seconds to tens of seconds, chemical plants and nuclear power plants can urgently close solenoid valves or shut down reactors, running high-speed trains and trains can be braked urgently, low-floor residents can be evacuated to the outside of the building, and high-floor residents can take refuge next to solid objects.
Q：微信、QQ推送快不快？
A: The biggest demand for earthquake early warning is fast. The Sichuan Provincial Earthquake Observatory has been connected to the official authoritative early warning data of the China Earthquake Early Warning Network, WeChat has set up an independent message channel that can be flexibly expanded for the earthquake early warning, and QQ has mature technical reserves for the high-concurrency message push of a large number of users.
Q: Are there any plans to launch more places?
A: Yes! Hold your horses. Under the guidance of the China Earthquake Administration, a national WeChat earthquake early warning service platform is being developed, which has now entered the internal testing stage and will soon be launched nationwide. QQ's city-wide earthquake early warning function will gradually cover more provinces.
