Secondary geological disasters

Secondary geological disasters refer to landslides and mudslides caused by strong earthquakes; The breach of the dam embankment causes floods, and the collapse of the mountain may block the river and form a dammed lake, which will cause floods after collapse; Epidemic plague after the earthquake; The ignition of flammable and explosive substances causes fire, explosion or toxic gas leakage due to pipeline damage, and the spread of bacteria and radioactive substances poses a threat to human and animal life.

How to deal with emergencies

■ When the house is facing a landslide, it should be evacuated immediately; When a landslide occurs, do not run along the sliding direction of the landslide, but run to both sides of the landslide.

■ If you find signs of debris flow, you should immediately observe the terrain and run to the slopes or highlands on both sides of the valley. Don't hide under steep slopes with rolling stones and a lot of deposits, don't stay in low-lying places or climb up for shelter.

■ In case of collapse during driving, you should leave the section with slope quickly; When the traffic jam is caused by collapse, you should obey the traffic command and accept the guidance in time.

■ Keep abreast of the safety information of dams and dammed lakes in the earthquake zone, and evacuate the danger zone immediately after being informed.

■ In case of fire, lie on the ground and cover your mouth and nose with a wet towel. To move to a safe place after an earthquake, you should crawl and go against the wind.

■ When toxic gas leaks, don't run in the downwind direction, try to go around to the upwind direction, and try to cover your mouth and nose with a wet towel; In case of gas leakage, cover your mouth and nose with a wet towel, and never use an open flame.

■ Pay attention to food hygiene and don't use polluted water sources. If you are bitten by mosquitoes, deal with it immediately, and don't scratch it. Before meals and rest, it is best to disinfect the skin exposed outside the clothes (commonly used medical disinfection water includes hydrogen peroxide, iodine, peracetic acid, etc.), and regularly disinfect the environment and bedding.

Special tips

■ Be familiar with evacuation routes and early warning signals.

■ When there are signs of landslides and collapses in nearby mountains, they should immediately report to the local government or relevant departments, and notify other threatened people.

■ The construction of disaster shelters and new houses should be quite far away from the landslide and debris flow areas. When hidden dangers of geological disasters are found, they should be moved and avoided immediately.

■ Shock absorbers should be kept away from large canals and banks of river banks to avoid being attacked by floods. Strictly avoid building earthquake-resistant sheds in downstream rivers.

■ In summer flood season, when you go for an outing in suburban canyons, you must listen to the local weather forecast in advance, and don't enter mountain valleys after heavy rain or even rainy days.

■ You can't take shelter from rain, rest and walk on concave steep slopes and places where dangerous rocks stand out, and you can't climb dangerous rocks.

■ When playing outdoors in mountainous areas, you should choose a flat highland as the camp, avoid the curved concave bank of the river (ditch) or the narrow convex bank with low height as much as possible, and never build a camping tent at the ditch or the low level in the ditch.
