Earthquake Tips

Earthquake, also known as earthquake and ground vibration, is a natural phenomenon in which the earth's crust vibrates during the rapid release of energy, 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.

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.

Earthquake precursors

Precursors refer to abnormal phenomena that occur before an earthquake occurs:

1. Well water and spring water are deformed, and spring sources suddenly dry up or gush out. Signs;

2. Animal early warning, for example, jellyfish in the ocean can predict storms; rats can avoid mine collapses in advance, etc.;

3. Animal abnormalities include cows, horses, donkeys, The mules were frightened, refused to enter the stables, refused to eat, barked, fought in groups, broke their reins and ran away, kicked and dug the ground, and suddenly ran away while walking.

Prevention before earthquakes

1. Clean the corridors and evacuate under the bed to provide emergency shock absorbers;

2. Pillows and cushions are wonderful for cushioning. Earthquake "helmet" can protect your head from being hit;

3. You must have an earthquake emergency kit, first aid kit and fire extinguisher at home, and learn to use them;

4 .Learn to use gas valves and electric switches, and remember to close them when an earthquake comes;

5. Regularly reinforce the ceiling, bookshelves, and wardrobes at home to prevent people escaping from being injured when an earthquake comes;

6. Be familiar with the evacuation sites and evacuate to safe areas quickly in case of emergency;

7. Carry out appropriate drills at ordinary times to avoid casualties caused by panic during earthquakes;

Epicenter emergency response

1. Hide and wait: When you cannot escape from a major earthquake, you should lie down in a safe corner such as under the bed or table, protect your head with a pillow, and evacuate quickly when the situation becomes slightly stable;

2. Evacuation from high-rise buildings: You should take safe passages, and it is recommended not to take the elevator;

3. Shock absorption in public places: Suitable for theaters, rows of chairs in gymnasiums, columns and corners of shopping malls, etc. The shock absorber should avoid areas that are prone to collapse such as shelves;

4. Classroom evacuation: Do not run around blindly. It is very easy for people to be crushed to death and injured. Move outdoors under the instruction of the teacher. If there is no time to move, you should protect your head, hide under the desk, and wait for the opportunity to evacuate;

5. Escape from the fire: Cover your mouth and nose with a wet cloth, and crawl against the wind to escape from the fire;

Post-earthquake first aid

1. Rescue principles: save lives first, treat injuries later;

2. On-site first aid techniques: cardiopulmonary resuscitation and trauma first aid

3 .Cardiopulmonary resuscitation: First aid measures taken for patients with cardiac or respiratory arrest to help them restore their circulatory system, spontaneous breathing, and consciousness;

4. The four steps of cardiopulmonary resuscitation: Judgment—Calling for help—Compression—Defibrillation

5. Trauma first aid: If the injured person is found to be bleeding severely, the bleeding must be stopped immediately to avoid death from shock caused by heavy bleeding.

6. The four major first aid techniques for trauma: hemostasis - bandaging - fixation - —Transportation
