Meteorological expert tips: Main points of disaster avoidance such as heavy rain and debris flow

At present, the southern provinces of China are in the main flood season, with frequent heavy rains and associated secondary disasters such as landslides and debris flows. To help people enhance disaster prevention and mitigation awareness and self-protection capabilities, experts from the China Meteorological Administration introduced the knowledge of emergency and risk avoidance for disasters such as rainstorms and debris flows.
When heavy rains and heavy rain disasters occur, meteorological experts remind people: First, pay attention to listening to local weather forecasts and learn about early warning information in time, and be prepared for possible disasters; Second, residents with low-lying houses should move to Safe location; third, drive and remember not to walk on unfamiliar stagnant water roads, anchor in low-lying places, and immediately leave the vehicle to high places for rescue.

For disasters such as mountain torrents, debris flows, and landslides caused by heavy rain, experts introduced methods for judging the occurrence of debris flows: At first glance, the normal flowing water in the river (ditch) bed suddenly stopped or the flow suddenly increased, and more firewood, Trees can confirm that debris flows have formed in the upper reaches of the river (ditch); on second hearing, the sound of train roars or thunderous thunder from deep valleys or trenches, even very weak, can be considered that debris flows are forming. In addition, the deep valley becomes dim, accompanied by a roar or a slight sense of vibration, which also indicates that a debris flow has occurred in the upper valley.

The experts also introduced the main points of risk avoidance when encountering torrents or debris flows: first, when torrents or debris flows are found, keep calm, do not run upstream or downstream along the valley, and climb the slopes on both sides of the valley; second, Never cross the debris flow or wading across the river; third, people who have evacuated the danger zone before the debris flow occurred. After the rainstorm stops, do not rush to return to the ditch to stay in the land, you should wait for a while.

If you are involved in the flood, you should keep calm, find and catch a floating object as soon as possible to help float; if the rescuer cannot swim, you can not force the water to save people, you can use a life buoy, bamboo poles, etc. to help the person who fell into the water; Try to keep the drowning person's nose and nose out of the water as much as possible. After rescuing the water, hold his waist and abdomen with his back up and his head hanging down to pour water; if breathing stops, artificial respiration should be performed immediately, if the heart stops, he should Perform chest compressions first.
