CCTV News: May 12 is the 16th National Disaster Prevention and Mitigation Day, and this year's theme is "Everyone Stresses Safety, Everyone Knows How to Respond to Emergencies - Strive to Improve Grassroots Disaster Prevention and Risk Avoidance Capabilities". In the flood season, strong convective weather occurs frequently, and it is easy to cause geological disasters such as landslides, landslides, and debris flows in mountainous areas. However, these geological disasters are often preceded by some signs. How to capture these early warning signs in time and avoid danger scientifically? Let's take a look at the strategy.
What are the signs before a geological disaster occurs?
Before a landslide occurs, the soil at the front will suddenly rise violently and burst into cracks, or even local landslides and orderly cracks, and groundwater will gush out along the squeezing cracks.
Before the mountain collapses, there will be rock fragments falling off the mountain wall, and the sound of tearing and rubbing can be heard from the depths of the mountain.
The warning of debris flow is more obvious, the water level in the valley will rise sharply, the river will suddenly stop flowing or the flood will surge. The depths of the ravine were dim and incomprehensible, accompanied by a deafening roar, and even a slight tremor of the surface could be felt.
How to save yourself in the event of a geological disaster?
In the event of a landslide, collapse or mudslide, move quickly to a safe high ground, do not take shelter or stay under a low-lying valley or steep hillside, do not run upstream or downstream in the direction of a ditch, and flee to the slopes on both sides perpendicular to the disaster.
How to ensure safety when driving in the event of a geological disaster?
If there are cracks, deep ditches, or signs of water on the road, or cracks in the walls of bridges and tunnels, the water level of the bridge has submerged the piers, and the water in the tunnel has submerged the wading line, be sure to stop the police immediately and do not risk passing.
How to deal with a tornado?
Severe convective weather is prone to tornado disasters in plain areas. When encountering a tornado outdoors, leave it from the side or back. If you don't have time to dodge, quickly find an open depression and lie down.
If you encounter a tornado while driving, you should try to get out of the car immediately and escape. If the tornado is far away, but the crosswind is strong, hold the steering wheel of the car with both hands, keep the correct driving direction, and do not brake suddenly. If you are experiencing a tornado in your home, avoid doors and windows.
