Earthquake prevention slogans

Earthquake prevention and disaster relief are not slogans, putting them into action is the most important thing.

Prevent disasters early and reduce major disasters; treat disasters early and suffer less disasters.

Don’t forget that disaster prevention costs money. Reduce losses and pay back twice as much.

Earthquake prevention and disaster relief, environmental improvement, and disease prevention.

Pay attention to drinking water hygiene and do a good job in epidemic prevention and control.

We are united in our efforts to provide earthquake relief and rebuild our homes!

Implement emergency plans and maintain public safety.

We are united as one, dedicating our love to support the disaster-stricken areas!

Disasters can hurt people and damage money, but disaster prevention will save you trouble.

Scientific earthquake prevention can reduce losses, but it is inevitable to ignore the crime of earthquake prevention.

Participate in earthquake prevention and disaster reduction and build a harmonious society.

The entire population is mobilized for disaster prevention and everyone participates in disaster reduction.

Communist Party members must always be at the forefront of earthquake relief donations!

Everyone should raise awareness of earthquake prevention and resolve earthquake hazard risks everywhere.

Disasters can be prevented, but lives cannot be reversed.

Sustainable development requires earthquake prevention, and putting people first requires disaster reduction.

Introduction to earthquakes

Earthquakes, also known as earthquakes and ground vibrations, are vibrations caused by the rapid release of energy in the earth's crust, during which seismic waves are generated. The collisions between the plates on the earth cause the edges of the plates and the interior of the plates to move and rupture, which is the main cause of earthquakes. The place where an earthquake begins is called the source, and the ground directly above the source is called the epicenter. The place where the ground vibrations of a destructive earthquake is strongest is called the epicenter, and the epicenter is often the area where the epicenter is located. Earthquakes often cause serious casualties, can cause fires, floods, toxic gas leaks, spread of bacteria and radioactive materials, and can also cause secondary disasters such as tsunamis, landslides, collapses, and ground fissures. According to statistics, more than 5 million earthquakes occur on the earth every year, that is, tens of thousands of earthquakes occur every day. Most of them are too small or too far away for people to feel; there are about ten or twenty earthquakes that can really cause serious harm to humans; there are about one or two earthquakes that can cause particularly serious disasters. Earthquakes that people cannot feel can only be recorded with a seismograph; different types of seismometers can record earthquakes of different intensities and distances. Thousands of various seismic instruments are operating around the world to monitor earthquake movements day and night.

Earthquake self-rescue methods

Hide under tables and other sturdy furniture. The duration of large shaking during an earthquake is about 1 minute. Take shelter under a sturdy table with a low center of gravity and hold on to its legs. In situations where there is no table or other places to hide, you should also use cushions and other objects to protect your head.

Turn off the fire immediately when shaking, and extinguish the fire immediately if it breaks out. During an earthquake, turning off and extinguishing fires are important factors in minimizing earthquake disasters. There are three opportunities to turn off the fire. The first opportunity is during the small shaking before the big shaking. The second time is when the big shaking stops. The third time is after the fire is started. Even if a fire occurs, at 1 -It can still be put out within 2 minutes.
