In addition, residents in some of China's most frequent areas have also installed special terminals for early warning systems in their homes. It's like a small TV screen, and once it's coming, early warning messages such as the countdown to the arrival of the wave will appear on the screen, reminding the user to avoid danger quickly.
*Is the warning a forecast?

Expert presentation. An early warning is not a forecast but an alert.
Receive an early warning message indicating that it has been **.
It refers to after the occurrence of **.

Generally, it is only a few seconds to tens of seconds.
It can fight for emergency disposal and evacuation time for the public.

Researcher Gao Mengtan said.
*The principle of the use of the early warning system is:
By encrypting the Taiwan network in the most frequent areas.
When it happens, take advantage of these dense networks.
In a relatively short period of time.
You can determine the size and location of the **.
Calculate the intensity of the impact of **.
The intensity of different regions can be calculated.
Uses electromagnetic waves, in a very short time.
It can send an early warning to all places.
Alerts received by different people.
*The arrival time of the transverse wave and the distance to the epicenter are different.
What is the reason for this?
Gao Mengtan said. From the principle of the current early warning system.
and ** wave propagation speed and range of influence.
The length of warning time is limited.
*The length of the warning period.
Depends on how close the area is to the epicenter.
The closer the area is to the epicenter, the shorter the warning time.
Generally near the epicenter.
The time to provide early warning is almost zero.
That is, there is a blind spot in early warning.
How to avoid danger after receiving ** warning?
These are the key points to master!
* Early warning information can be after the earthquake.

Even tens of seconds of hedging time.
What should be done in this short period of time?
First of all, when it happens.

are extremely dangerous and must be kept away.
If you're indoors.
Buildings should be evacuated as soon as possible.
Run outside into an open area.
If the floor is too high or the time is very tight.
Too late to leave the room.
Be sure to pick up a cushion or pillow as soon as possible.
Cover your head and bend down to lower your center of gravity.
Hide in a small, open, load-bearing room with a wall.
And firmly grasp the firm object to prevent shaking.
Wait until the tremor is over, and then quickly flee outside.
If you are outdoors yourself.
Be mindful of your surroundings.
Stay away from tall buildings such as buildings, overpasses, billboards, etc.
At the same time, you should also be careful of high-voltage lines, utility poles and other equipment.
Choose an open area nearby to avoid danger.
In extreme cold weather**.
What to look out for?
If you encounter such a cold weather recently.
In the process of escaping and self-rescue.
It is also necessary to strictly prevent acute frostbite and hypothermia.
Especially hypothermia!
Because once hypothermia occurs.
If you don't get timely help.
It could lead to the death of those trapped.
Hypothermia. It refers to the fact that the heat loss of the human body is greater than the heat supply, which reduces the temperature of the core area of the body, and causes a series of symptoms such as chills, confusion, cardiopulmonary failure, and even eventually death. Generally speaking, if the core temperature of the human body falls below 35 degrees Celsius, it is medical hypothermia, that is, hypothermia.
Stack the risk of hypothermia.
How to save yourself trapped in the ruins?
First of all, ensure the smooth flow of the airway. Be careful to cover your mouth and nose with clothing to prevent suffocation caused by soot. If the limb is crushed, carefully drag it out. If that doesn't work, move the debris slowly and find a way to fix the oppression. Gather some drinkable water whenever possible. The injured person should be pressed in time to stop the bleeding or make a simple tourniquet to stop the bleeding. It is very likely that the trapped person will be trapped for more than 72 hours, so it is important to have a strong will and build mental endurance.
For people with hypothermia, changing into dry clothes is key. Because the extremely cold environment and wet clothing can cause a person's core body temperature to be lost quickly. But don't say it's buried in **, even if you're walking on the street, it's hard to suddenly find a dry outfit. In the rubble, people with hypothermia will be more defenseless in the face of hunger and thirst, so severe hypothermia is the most dangerous cause of death in compound injuries.
If you are at risk of hypothermia, it is recommended that the trapped person do not cry and save energy. It's actually a way to save body temperature. If you can't find more clothes to keep warm, you can also hold two or more people as close to your body as possible and hug each other to resist the cold. At the same time, it should be noted that if the body is exposed to extreme cold, it will soon become numb and hard, whitish, waxy or grayish-yellow, at this time the action should be gentle, the latest scientific first aid standards do not recommend rubbing the frostbite area, not only can not relieve frostbite, but may cause more serious additional damage.
The more desperate the situation, the more you should stay calm. At night, gently tap the water pipe or wall with your hands or hard objects, and if a professional team detects the sound at this time, you can find the trapped person as soon as possible.
May the people in the disaster area be safe!
