Will the earthquake warning mobile phone inform you?

Will notify the earthquake warning mobile phone.

Many people think that the "earthquake warning" messages popped up by domestic mobile phones such as Xiaomi, Huawei, OPPO and vivo are all the credit of mobile phone manufacturers. In fact, our mobile phone is just a "window". This mobile phone is more connected to the China earthquake early warning network jointly built by Chengdu Institute of High-tech Disaster Reduction and China Seismological Bureau, and realizes early warning with the data provided by it.

As for the principle, in fact, it is to use the principle that radio waves are faster than seismic waves to send alarm information to the area around the earthquake center to inform people at different distances in advance of the time and place where seismic waves will arrive, so as to minimize the losses in the earthquake-affected areas.

Therefore, the closer to the earthquake center, the shorter the early warning time and the shorter our response time; On the contrary, the farther away from the earthquake center, the longer the early warning time, and the longer we can respond, which is equivalent to the "time difference" of the earthquake.

Earthquake early warning information from other countries

Take J-Alert in Japan as an example. When Japan Earthquake Administration or Meteorological Agency and other related institutions detect an earthquake, they will take the lead in transmitting the alarm information to major operators, and then the operators will broadcast the alarm information to the Apple iPhone in the earthquake zone. However, China does not have national communication early warning measures such as J-Alert in Japan and EAS in the United States, and mobile phones such as Apple and Samsung cannot be accessed.

Of course, for example, the China Earthquake Early Warning Network, which was jointly built by Chengdu Institute of High-tech Disaster Reduction and China Seismological Bureau, is connected by domestic mobile phones. In fact, Apple, Samsung and other mobile phones can be connected as long as they want, but there is no access option.
