On May 12, the Mini Program was upgraded and optimized.
Multiple destinations can be set
Added earthquake alerts
Added the multi-location alarm information aggregation page
At the same time, the QQ platform has also officially launched the earthquake early warning function. This also means that Tencent's dual-platform earthquake early warning covers the whole province of Sichuan. At present, Sichuan has achieved the ability to issue earthquake warnings for earthquakes of magnitude 5 or above in the province 5-15 seconds after the earthquake.

Is earthquake early warning useful? Fast?
Here comes the answers to these questions you care about
↓↓↓
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, 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.
