Tips for preventing earthquake disasters

1. Earthquake knowledge

Earthquakes are a natural phenomenon. At present, Lieren cannot prevent earthquakes from occurring. However, we can take effective measures to minimize earthquake disasters.

As the earth continues to move, it gradually accumulates tremendous energy, causing sudden cracks or misalignment of rock layers in certain vulnerable regions of the earth's crust. This is an earthquake.

Earthquake precursors refer to anomalies that occur before an earthquake, such as seismic activity, significant changes in the earth's surface, and geophysical anomalies such as geomagnetism, geoelectricity, and gravity, and abnormal behavior of groundwater levels, hydrochemistry, and animals.

Earthquake intensity is the degree of earthquake damage to the ground, buildings and structures at different distances from the epicenter. China divided the earthquake intensity into 12 degrees. Earthquake intensity and earthquake magnitude are two concepts, such as the Tangshan 7.8 magnitude earthquake, the earthquake intensity of Tangshan City is 11 degrees, the intensity of Tianjin downtown is 8 degrees, and the intensity of Shijiazhuang is 5 degrees.

3 degrees, a few people feel it.

At 4-5 degrees, the sleeping person wakes up and the chandelier swings.

At 6 degrees, the vessel fell and the house was slightly damaged.

7-8 degrees, house damage, ground cracks.

At 9-10 degrees, bridges and dams were damaged, houses collapsed, and ground damage was severe.

11-12 degrees, devastating destruction.

2. Emergency response to a sensed earthquake

A sensed earthquake refers to an earthquake that occurs at a relatively low earthquake level, has a significant sense of earthquake, and does not cause damage or major damage.

Emergency points

â—‹ After a sensed earthquake occurs, if the indoor personnel do not know the intensity of the earthquake at the moment of the quake, they should quickly evacuate in accordance with the pre-selected safer indoor suspension points.

â—‹ Quickly withdraw to the outdoor after the earthquake, pay attention to listening to and watching relevant news broadcast by TV stations and radio stations, and make preparations for earthquake prevention.

â—‹ Understand the trend of earthquake situation, do not listen to letters and spread rumors to ensure social stability.


3. Destructive earthquake emergency action

A destructive earthquake refers to an earthquake that occurs at a relatively large magnitude, causing a certain number of casualties and building damage or causing major casualties and building damage.

Emergency points

â—‹ People living in bungalows should quickly evacuate outside if there is a large outdoor earthquake, try to avoid tall buildings, overpasses, and stay away from high-voltage lines and chemical or gas factories or facilities; they can hide when they have no time to run Under the table, under the bed and next to sturdy furniture, cover your mouth, nose, dust and smoke with a towel or clothing.

â—‹ Residents living in buildings should choose small spaces such as kitchens and toilets to avoid shocks; they can also hide inside the roots, corners, and solid furniture of places that are easy to form a triangular space; stay away from external walls, doors, windows and balconies ; Don't use the elevator, let alone jump.

â—‹ Turn off the power and fire source as soon as possible.

â—‹ When you are in class in the classroom, working in the workplace, or performing activities in public places, you should quickly wrap your head, close your eyes, and avoid under the podium, desk, workbench, and office furniture.

â—‹ When you are in the wild, try to avoid the foothills and steep cliffs to prevent rolling stones and landslides. In case of landslides, you should run away from the direction of the rolling stones.

â—‹ When you are playing by the sea, you should quickly stay away from the sea to prevent the tsunami caused by the earthquake.

â—‹ When driving, you should quickly avoid overpasses, steep cliffs, telephone poles, etc., and choose an open place as soon as possible to stop immediately.

â—‹ When your body is injured by an earthquake, you should try to remove the objects pressed on your body, cover your mouth, nose, dust and smoke with a wet towel as much as possible; hit the object with stones or iron to contact the outside world, do not call for help, Pay attention to preserving physical strength; try to support unstable heavy objects above with bricks and stones to protect your living space.

4. Never panic during an earthquake

Most of the earthquakes we feel are sensational and strong sensational earthquakes, a few can cause minor damage, and very few earthquakes cause severe damage. Therefore, avoid panic when encountering an earthquake, calm down and take corrective action quickly. Especially in tall buildings and crowded places, it is the most realistic to avoid on-site. There was an earthquake in our country that did not cause any damage, but panicked people crowded and trampled on each other, causing serious injuries and even death.

â—‹ Don't jump

â—‹ Caring for each other

â—‹ Don't be crowded in crowded places

â—‹ Students should obey the command
