The new MIUI 11 feature will alert users with a pop-up. Xiaomi will be helped by research centers to analyze earthquakes in depth
Xiaomi will hold a press conference on September 24th to release a couple of 5G devices, as well as Xiaomi TV Pro and Xiaomi MIUI 11. Today, Xiaomi Product Director and MIUI Experience General Manager have announced an SOS Xiaomi MIUI 11 function in advance: earthquake warning .
The earthquake warning function uses a pop-up window to send a reminder to users. Remind users when the network detects an imminent earthquake that could cause strong ground shaking. It will also identify the position of the seismic wave, the area of the epicenter and the magnitude of the earthquake. At the end of the countdown, an emergency help service will be provided.
Xiaomi will introduce the functionality in MIUI 11
Earthquake seismic waves come in three forms: longitudinal waves, transverse waves and surface waves. The speed of propagation of longitudinal waves is high, about 5.5 km-7 km per second, but the destructiveness is reduced. The destructiveness of the transverse wave is great, since it makes the ground vibrate before and after the passage of the wave.
The surface wave is the slowest and can only propagate along the soil surface. The principle of the "early" earthquake warning system is to use the time difference from the fastest propagation waves to make predictions.
Theoretical studies have shown that if the warning time is 3 seconds, the victim ratio can be reduced by 14%. If it is 10 seconds, the casualty ratio is reduced by 39% whereas if the warning time is 20 seconds, the victim ratio can be reduced by 63%.
The prediction of the earthquake is much more complicated than it seems. If Xiaomi is developing such a function, it will take more than laboratory studies to confirm its authenticity. However, since these are alerts in seconds, accuracy could really improve. This functionality seems decidedly ambitious.
