Many people used their cell phones for several years and didn't know that they had a free life-saving feature inside them, which was earthquake warning。
Many of those who have experienced earthquakes have shared their true experiences, sleeping in the middle of the night, their mobile phones suddenly sound sharp alarms, and the red countdown of the screen shows how many seconds the wave has arrived, just a few seconds to dozens of seconds to get themselves a safe response. But in reality, the majority of ordinary users, this feature is automatically closed. Many people think that earthquake early warning requires spending money to download software, or that cell phones are available only in specific areas. In fact, most of the country's mainstream mobile phones are equipped with this service, all of which are free of charge, but are hidden in the setting, and many do not have access。
It is important to clarify here one of the most confusing concepts: earthquake warning is not equivalent to earthquake forecasting. Many would have misunderstood the idea that the function could predict when an earthquake would come a few days or hours earlier. To date, the world has no way of accurately predicting the timing of an earthquake。
The working logic of earthquake warning is that seismic signals are captured first after the earthquake has already taken place, at various monitoring stations. Earthquakes occur with two waves, one fast but small in destructive power, called vertical waves; and the other slow, but devastating, called crosswaves. When the system captures the signal, and at the speed of the electromagnetic wave, before the destructive wave reaches your location, the alarm is sent to your cell phone, giving it a few seconds to a few seconds to a few seconds to a few seconds to escape window. According to publicly available research data, an early warning time of three seconds would reduce casualties by 14 per cent; 10 seconds would reduce casualties by 39 per cent; and 20 seconds would reduce casualties by 63 per cent. Do not underestimate the shortness of a few seconds, and there are enough people to quickly hide under the table, far from the window window and avoid dangerous furniture。
But at the same time we need to look at this technology objectively, which is not almighty. In areas that are close to the epicentre, earthquake waves arrive at short notice, leaving no time for alarms; network signals are poor, mobile phone systems are too low, and there is a risk of underreporting, delay, failure to rely 100 per cent on mobile alarms, which are only our aid to avoid them, and they still need to be judged in the light of the actual situation on the ground。
I'll show you how to start an earthquake alert
The functional access points vary widely among different branded mobile phones, many of which are unable to go through the settings. If the menu is not available, there is a small, altruistic technique to open the cell phone to set the top search box and enter the keyword “earthquake alert”, the system will jump directly to the corresponding function page, save the difficulty of flipping over the menu one layer, the version of the system is different and a small number of machine menu names will vary slightly。
Wigand, glory cellular
Operating path: open settings, find [safe], point in [emergency alert], just open an earthquake warning switch。
Once on, the system will require the granting of location privileges and will have to select the location allowed. At the onset of the earthquake, the hand was given the opportunity to play the countdown voice aloud, while the vibrations continued, the screen pops out of the early warning window, accompanied by a search for a nearby shelter and an emergency help entrance. Note that this feature is not available in the old version of the system and that if no access is available, the mobile phone system can be updated to the latest version。
Mi, redmi red mi
Operating path: open the [cell phone housekeeper] on the desktop, move down to the page, find the [family care] board, click in, select an earthquake alert, click on the service。
Some of the new versions of the system, the entrances will be placed in the universal toolbox. After the opening is completed, you can click on the “warning demonstration” on the page to test the sound of the alarm and the effect of the bullet window, to get to know what the alarm looks like in advance, and to avoid sudden alarms when the situation is real。
Oppo, 1+, real real-realme phone
Operating path: set up sos emergency contact for natural disaster alerts and earthquake alerts and turn on the switch。
This function is not available when the version is too low. Upon opening, voice alarms can be removed from the bullet window and can also be set up to synchronize flashlights, even if the cell phone is silent, to receive the alarm through the light alert。
Vivo, iqoo phone
Operating path: open the mobile phone [weather app], click an icon for the top right corner gear style, find an early warning for the earthquake and activate the seismic warning service。
There are a few new versions of the vivo, and access can also be found directly in the system-set security blocks. It is important to remind that the powers must be given to notifying and locating, and if they are denied, to open the switch without receiving any warning。
Apple iphone
National apple phones, the system does not have a full seismic warning function and cannot be activated directly in the settings. Sound approach, open app store, search for officially certified “earthquake alert” app, download installation. Upon completion of the installation, the app is opened to allow notification, location, backstage repainting of privileges and to ensure that the app is not killed by the system backstage, so that it can receive the alert information。
Samsung and other small brands
The national star can locate emergency alarm plates in settings -- security and emergencies. If seismic warning options are not available in the menu, the system is not built-in and goes directly to the application store to download official alert apps and not to download undisclosed billing software。
Here is a key point: the formal earthquake warning service is free of charge. It is unreasonable for some of the web-based apps to collect membership fees in the name of earthquake alerts, claiming that vips are given priority over warnings, that public services for earthquake warning provided by the state are free of charge and that there is no priority to pay for such services。
There's no built-in, no backup, no cell phones
Some old mobile system versions are too low, and the upgrade system does not have the means to incorporate earthquake warning, do not need to change mobile phones, and there are common channels for receiving early warning that are suitable for all aircraft types。
First of all, we're going to have a little wi-fi. A micro-mail search of the “china seismic network” applet, followed by an open earthquake warning, allowing access to location, notification, and adding to the city where you live, can receive an early warning if you do not have to download an ap. The disadvantage is that if the back office is cleared, there is a risk that the message will not be received, that it will be suitable as a backup option and that it will not be a complete substitute for a system-level warning on mobile phones。
Second, tv, web top box. In many parts of the country, iptv television has access to earthquake warning services, and when the earthquake occurs, the television is shown directly in the window, and the elderly do not operate smartphones and are warned when watching television。
Third, radio. In some parts of the country, emergency radio broadcasts are synchronized to send early warning messages of earthquakes。
When the earthquake alerts, these things must be done or nothing
Many people responded that the earthquake warning had been opened, but no warning had been received at the time of the earthquake, and that most of the cases were not dysfunctional, but did not have a mandate。
First, access must be allowed. Earthquake warning needs to know where you are in order to determine how long the wave will reach you. Sets the permission to " allowed only for the duration of use " without setting a ban on positioning. Disable position, function is directly disabled。
Second, all notice privileges are open. Not to classify an earthquake warning notice as silent, to close the notice, to allow silent notice, and to fire windows and alarms even if a signal is received in the back office. Many users are accustomed to turning off most of the ap circulars and must release notification privileges to the early warning function alone。
Third, no restrictions should be placed on back-office activities. The third party, the ap version, needs to be allowed to run backstage, and the cell phone saver strategy does not set the ap as “prohibiting backstage activity” and the power saver mode kills the ap and does not receive the transfer。
Fourth, cell phones don't break off for long. Seismic early warning relies on a signal from the network, which is not operational in the absence of a network at all。
Fifth, upgrade the mobile phone system. The factory chambers of commerce continue to optimize the early warning function and there will be gaps in the old system, and it is recommended that the official version be updated regularly。
A lot of people wonder if the cell phone is silent, it's static, it's not disturbing. The country's mainstream andrehong type, with earthquake warning as a national emergency notification, is still forced to trigger the sound and vibration of the alarm, even if the cell phone is silent, without disturbance. It is important to note that apple cell phones are equipped with third-party aps, depending on the ap privileges and that, in some cases, no-disturbing mode suppresses the alarm。
What do we do? Learn to understand early warning, learn to avoid danger
When the mobile phone emits an earthquake warning, it shows an estimated seismic level, distance, and number of countdown seconds. The way they are handled is different from the time they count down, and the alarm goes off。
If the countdown is more than a dozen seconds away, the buildings are not high and the surrounding environment is safe, an orderly evacuation can be made to the outer space area in order to ensure that it is not hit by a crash。
If you have only a few seconds left in the countdown, or if you're in a high-rise building, don't take the elevator, don't rush down the stairs blindly. It's easy to fall and get hurt when the stairs are swayed. (b) to avoid imminent danger, in accordance with the principles of “voiding, covering and holding hands”, to sit under a solid table and to guard the head with both hands, away from windows, chandeliers, cabinets and refrigerators, which can easily be dumped, and to avoid the balcony, glass curtain walls, and then to evacuate in an orderly manner to a safe position when the shaking is complete。
In the bedroom, immediately away from closets, chandeliers, windows; in the kitchen, away from stoves to prevent gas leaks; and in the halls, elevators, immediately find a safe place to hide。
If you are outside, you receive early warning and move quickly away from the building, billboards, utility poles and walls to the open and flat。
It should also be borne in mind that the seismic level and countdown of the early warning window is a rapidly measured estimate, which is constantly revised and subject to minor errors, which are a normal technical phenomenon, and that the number is not completely ignored。
Every day, you can open a warning demonstration on your cell phone, and experience a sound of alarm, and families, especially the elderly and children, are encouraged to do it, so that there are no surprises。
Give the old man a cell phone and put an earthquake warning
Many senior and middle-aged friends are not familiar with mobile phone settings and do not find their own functionality. When young people are free, help their elders with their cell phones turn on the earthquake alert, check the location and notify them of the full access. Old people have a bad memory. They don't have to remember complex paths, just help them set up ahead。
A number of older persons sleep with silenced mobile phones, confirming that their emergency alerts are not restricted by silence. If the old machine is used by the elderly and the system has no built-in functionality, the official app is installed, along with the micro-intelligence sub-program, with double backup。
In addition to mobile phones, the home can simply prepare emergency supplies, with mineral water, small quantities of dry food, flashlights, whistles, places at hand where they are available and ready。
At the end
Earthquake warning is not one-size-fits-all; it does not stop an earthquake or 100 per cent zero error, but it is a free security guaranteed by modern technology to ordinary people. It takes just a minute or two to get this function open, with an extra chance of survival at a critical time. Do not think that there will be no earthquakes in their own region, and there will always be uncertainty about the geology, preparedness and preparedness。
