Smartphones Xiaomi and Redmi warned of yesterday’s earthquake in China



On April 16 at 16:06, an earthquake with a magnitude of 4.3 with a depth of 9 kilometers occurred in Luanzhou County, Tangshan City District, Hebei Province.

According to the China Earthquake Network, the epicenter is 47 kilometers from Tangshan City, 150 kilometers from Tianjin City and 198 kilometers from Beijing. In these cities, there were very obvious tremors.

After the earthquake, users posted gratitude to Xiaomi and MIUI developers on social networks. The fact is that many of the company’s smartphones have an earthquake warning system. For example, user Redmi K40 confirmed that his smartphone warned of an earthquake in more than ten seconds and gave an alarm.

Xiaomi officially launched this feature back in 2019 and it works on mobile phones, TVs and other company products. Xiaomi became the first manufacturer in the world to offer this functionality to its users.

The warning is not made on assumptions, and not on the basis of the principle that radio waves travel faster than seismic waves after an earthquake. Before destructive seismic waves reach the target area, users can have anywhere from a few seconds to several tens of seconds to prepare for an impact. This helps to reduce the number of victims.
