[earthquake early warning function of Tencent Wechat and QQ platform launched] on May 12, on the occasion of the 16th anniversary of the Wenchuan earthquake, Tencent announced the official launch of its earthquake early warning function on both Wechat and QQ platforms, providing life support for residents of the whole province of Sichuan. Last year, Tencent partnered with the Sichuan Seismological Bureau to launch the WeChat Mini Programs earthquake early warning platform, and this year it has upgraded and optimized the platform with a number of new functions. < Last yearSlotsempirenodepositbonus2022On the basis of cooperation, Tencent upgraded WeChat Mini Programs this year, allowing users to set up multiple places of concern, add a quick earthquake warning function, and aggregate multiple alarm information pages. At the same time, the QQ platform has also officially launched the earthquake early warning function, and Sichuan Province has the ability to issue early warning 5-15 seconds after the earthquake. > < the opening mode of earthquake early warning function is very simple. On Wechat, users only need to search the official account of "Sichuan Seismological Station" and follow it to start earthquake warning through Mini Program. On the other hand, the QQ platform can be successfully opened by searching and following "QQ city-wide assistance", clicking on "earthquake early warning" and adding the early warning location and selecting the intensity range. > < the principle of earthquake early warning is to capture the longitudinal and shear wave signals produced when an earthquake occurs. The longitudinal wave speed is fast but the destructive power is small, while the shear wave speed is slow but the destructive power is great. When the seismic station captures the longitudinal wave signal, it will quickly transmit the epicenter location, magnitude and other information to the early warning terminal through the electromagnetic wave, so as to buy several seconds to tens of seconds of emergency escape time for the surrounding cities. Studies have shown that 3 seconds in advance can reduce casualties by 14%, while 20 seconds in advance can reduce casualties by 63%. In earthquake warning, time is life. Sichuan Seismological Station has been connected to the China earthquake early warning network, realizing the whole Sichuan coverage of earthquake early warning information in seconds. Tencent said it is developing a national Wechat earthquake early warning service platform and has entered the internal testing stage and will provide services to the whole country in the near future. QQ city-wide earthquake early warning function is also expected to gradually cover more provinces. >
