An earthquake warning will be issued 5-15 seconds after the earthquake
Earthquake early warning services in other provinces will be launched soon
Many netizens praised it
"This feature is real to use"
"A great feature that saves lives"
"This feature should be liked"
How to turn on earthquake warning on WeChat and QQ?

WeChat success warning
Reporters can see the page in the Mini Program to display real-time location and recent earthquake information
Warning position
Multiple points can be set
You can experience it after saving the settings
The earthquake early warning simulation demonstration shows the arrival time of seismic waves
Predict intensity, magnitude,
distance from the epicenter, etc
QQ search and follow QQ citywide help, click on the earthquake warning to add the warning location, select the intensity range to set it successfully
Is early warning useful? Is WeChat and QQ push fast? Tencent also responded▼
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.
Retweet to spread to more people!
