CTOnews.com news on August 7, recently, a 5.5 magnitude earthquake occurred in Pingyuan County, Dezhou City, Shandong Province, with a focal depth of 10 km. The earthquake was clearly felt in many provinces, including Beijing, Tianjin, Hebei, Jiangsu, Henan and other places. Many netizens said that they were woken up by the earthquake warning sound of mobile phones, televisions and other devices.

Earthquake early warning is a technique that makes use of the difference in the propagation velocity of seismic waves to warn in advance before the arrival of seismic waves. At present, almost all domestic mobile phone brands provide earthquake early warning functions, such as Huawei, Xiaomi, vivo, OPPO and so on.

However, some netizens found that the earthquake warning function of Xiaomi mobile phone is turned off by default and requires users to turn it on manually. This caused some netizens to wonder why such an important life-saving function is not turned on by default.

In response, Redmi mobile phone marketing manager Zhang Yu responded on Weibo that the scene and shape of earthquake warning itself is relatively special, and it is turned on by default before users are fully aware of the function. When the earthquake comes, it is likely to cause panic among users and lead to additional personal safety accidents, so after the function is turned on, you need to see a mandatory demonstration of the reminder, so as not to cause unnecessary panic.

Zhang Yu also said that as some cities do not support earthquake early warning function for the time being, his own method is to find other nearby cities to open for a rainy day.

In addition, if you want the earthquake warning function of the phone to trigger the alarm normally, there are two details to pay attention to: first, the phone must be connected to the Internet, which is the bottom line; second, when activated, the system ignores the volume state and screen brightness state of the phone. By default, the sound is pulled up directly, and the brightness of the phone is full, even if you do not bother.

Zhang Yu also introduced how to turn on the earthquake warning function of Xiaomi equipment, and CTOnews.com is attached below:

Mobile phone on: set up → search MIUI early warning Center / Mobile Manager → early warning Center.
