At 0:00 o'clock last night, Wuwei City, which is far away from Linxia Prefecture, also felt a clear earthquake, and the drying racks in the residential buildings swayed back and forth, making a loud noise. I rolled over and sat on the bed for a long time, and when I saw no more movement, I fell asleep again. This morning, I touched my mobile phone and looked at it, and sure enough, Jishishan County, Linxia Prefecture, Gansu Province, suddenly 6Level 2 Big**!
Jishishan County, belonging to Linxia Hui Autonomous Prefecture of Gansu Province, is located in the southwest of Gansu Province, Jishishan County is located in the southwest of Gansu Province, the full name of Jishishan Baoan Dongxiang Salar Autonomous County, is the longest county in the country, and the only multi-ethnic autonomous county in Gansu.
This time, Jishishan County, Linxia Prefecture, Gansu Province happened 6Level 2**, exactly 10 midnight. **Caused damage in three counties of Haidong City, Qinghai Province, which is adjacent to Jishishan County. So far, 105 people have been killed in Gansu and 13 in Qinghai, and some infrastructure such as water, electricity, transportation, and communications have been damaged.
It is said that such a level of ** should not cause such a large **, in this regard, experts explained that this ** is a thrust type rupture, the earthquake area is densely populated and the houses have poor earthquake resistance, and more importantly, it is too late at night to react and so on.
Compared with 2:28 p.m. in Wenchuan and 7:49 a.m. in Yushu, this time Jishi Mountain** is only 6Level 2, but it happened in the middle of the night, and many people were just falling asleep or asleep.
Objectively, it is too late to react, evade and escape, although the number of people we are currently praying for will not increase, but the cruel reality tells us that there must still be people buried under the rubble.
Some people on the Internet say that someone received an early warning on their mobile phone before, so they can predict it in advance. But there are also those who question it, and that's. So, is the mobile phone ** warning useful or not?The answer is yes, no matter how at a critical moment, even if it is just a few seconds in advance, it may be a matter of personal safety.
* early warning relies on the propagation of electromagnetic waves much faster than the first wave, and the first wave is also divided into longitudinal waves and transverse waves, the transverse wave vibration is larger but the speed is slow, the longitudinal wave vibration is weaker but the speed is fast, after the longitudinal wave is captured by the first instrument, the relevant personnel quickly calculate the first situation, before the arrival of the transverse wave, the use of electromagnetic waves with faster propagation speed to issue an early warning to the area that may be affected. That is to say, the core of the early warning is to use the difference in the propagation speed of radio waves and waves.
Generally speaking, the length of the warning time is related to the distance of the area from the epicenter, and the closer to the epicenter, the shorter the warning time. In the vicinity of the epicenter, the time to provide early warning is almost zero, that is, there is a blind spot for early warning.
Of course, this is an early warning, not a forecast!Warning is a place that has been determined to occur, sending a signal to the area that may be affected, and the forecast is more like an unpredictable prophet, or according to some factors, such as weather forecasting, which is a probabilistic event, at present, forecasting is still an unsolved problem in the world. Therefore, we can't be too harsh on the mobile phone ** warning, after all, opening it is still useful at some point.
So, how to open the mobile phone ** warning, the method is as follows. You can see if your mobile phone has opened the "** warning" function, according to the different mobile phone models, some brands of mobile phones need to go to the app store, search for the "** warning" keyword, and ** related apps by yourself. There are also some brands of mobile phones that need to go to the system "Settings", find the "Security" option, and then turn on the "**Warning" function step by step according to the prompts.
Maybe at a critical moment, turn on the phone's ** warning, and it can really work. Please tell each other, remember to turn on your phone** warning.
