A landslide is a sliding or displacement of rocks or soil masses under the influence of gravity. Most often, landslides occur on the slopes of mountains, ravines, and steep banks. Although the descent of a landslide is not as fast as the passage of a mudflow, it is no less dangerous. Therefore, everyone should know the rules of behavior in case of a landslide.
The main cause of landslides is the erosion of the lower layers of the soil. This is especially true when a layer of slippery clay lies on solid rock. Therefore, in case of prolonged rains or heavy rainfall, avoid visiting potentially dangerous places.
Another cause of a landslide is earthquakes or blasting operations carried out near places where a landslide may occur. Do not forget that the instability of the soil masses persists for several days after ground movements.
Pay attention to all movements of the clay mass. They are always signaled by small cracks in the inner walls, jamming of windows or doors, crackling of building structures, new cracks and crevices in the soil and on the asphalt. In this case, immediately leave the dangerous place and signal a possible landslide to the rescue service.
If you are in a landslide hazard zone and receive a threat signal, turn off the gas, electrical appliances, turn off the water and prepare for evacuation.
If you do find yourself in the area of an impending landslide, do not try to escape from it. The speed of soil movement can accelerate dramatically up to several meters per second. Move aside as quickly as possible, perpendicular to the slope along which the landslide is moving.
To test the safety of your route, grab a sturdy stick and sample any large rocks in your path before placing your foot on them. If you don't have a stick, try throwing small pebbles in front of you. A small blow is enough to cause the movement of the stone masses.
If you cannot get away from the landslide, and the ground movement overtook you, try to protect your face from blows, cover your head with your hands. Avoid large boulders and move away from them, in a small-fraction flow it will be easier for you to get out. Move in the direction of the ground and try to constantly as if to emerge closer to the surface.
If you get stuck in a blockage, don't panic. There are cases when people were taken out of the rubble a few days after the descent of the landslide. Check the condition of the limbs, wiggle your fingers and toes. While the debris is mobile, try to free up a small space in front of your face.
Give voice signals from time to time. During rescue operations, minutes of silence are set every hour to hear if there are still people in the rubble. Try not to fall asleep.
