Ideally, people want to know when the earthquake will happen and how much the loss will be.

In Japan and China, people always think that earthquakes can be predicted.

In Japan,

Laying wires on land and sea to monitor their activities.

The traditional practice of China people is to observe animals and plants to get early warning signals of earthquakes.

For example, people in China noticed that before the earthquake, hens would behave abnormally: they refused to enter the cage at night.

They also noticed that snakes would crawl out.

Freezing to death, dogs will bark, even ordinary dogs

Our dog barks, too.

Before the Hanshin earthquake in Japan, it was reported that a large number of fish swam to the surface.

Some birds, such as pigeons, also look very special.

It is said that the way they flew before the earthquake was different from that in peacetime.

Perhaps the most interesting and easy to measure is before the earthquake.

happen

Experimental data seems to show that before the earthquake

Radon content will increase.

People also hope to prevent major property losses caused by earthquakes.

You know, mostly underground.

All the people who lost their lives died in the collapsed building.

Therefore, earthquake resistance

Is the focus of attention.

Steel seems to be the best building material, but once it is welded into a rigid structure, it will not work.

Many new structures adopt a new steel joint method, I-joint, which seems to be the most durable joint.

This kind of steel joint will not break when moving.

Similarly, in order to prevent property damage,

When designing a building now, the pillars of the building will be the same as those of the building.

The strength is equal, and the column is deeply inserted into the solid foundation.

In addition, many new houses have adopted lighter roofs and solid walls.

Our cement column used to contain only steel bars, but now it is also covered with steel plates.

In addition to trying to improve

In addition, people in earthquake-prone areas also need to be prepared for possible major earthquakes.

They should regularly check and strengthen the houses, and put the heavy objects in low places.

And that door is reinforce to prevent accidental separation during an earthquake.

In addition to earthquake-proof houses, people in these areas need to take precautions for themselves.

They should store some water and food at home and at work.

It's best to reserve a few for each person.

Water.

Keep some.

and

It is also important to drink water from other sources safely.

Everyone prepares food for a week.

The earthquake rescue reserve also includes

Receiver, flashlight, spare battery, first aid supplies,

Tents, ropes and warm clothes.

In addition, the experts made the following suggestions:

Have at hand

You should put one in your residence, workplace and car (if you have a car).

It should be the kind that can put out any fire.

If necessary, prepare some special tools that can close the gas and water pipes.

Prepare a spare outdoor cooking and heating appliance, such as a portable camping stove and several small cans of gas.

Put a pair of heavy and comfortable shoes or boots in your residence, workplace and car.

There will be a lot of glass fragments in an earthquake.

Lightweight shoes can't protect your feet like heavy shoes.

Every family needs it.

Plan.

How to make a family leave safely in the chaos of the earthquake?

Everyone should agree with one

The rendezvous point outside-maybe in a town a few miles away.

Similarly, it is also important to negotiate the contact information of family members during the earthquake.

If there is an earthquake in a big city, many telephone lines in this city may be cut off.

The few available lines will be busy, because there will naturally be many calls after the disaster, and it will be difficult to call from one part of the city to another.

But maybe the phone outside the city is open.

The wise arrangement is for all family members to call their friends or relatives who live more than 0/00 miles away from/kloc to report their safety.

although

It is impossible to predict earthquakes at present, but they are increasingly aware of how large plates in the crust move, the pressure between plates, how earthquakes occur, and the general probability of earthquakes in a certain area.

In the near future, it will be possible to accurately predict earthquakes.

However, even if it can be predicted, people living in earthquake-prone areas should try their best to prevent disasters by building buildings that can resist.

House, at the same time, be prepared personally.

These preventive measures will play a great role in saving lives and preventing family losses.

Teach people how to do it effectively.

Survival should be the focus of all government planning and earthquake research projects.
