Avalanche Mudflow Rockfall

Today we talk about the dangers unique to mountainous regions. Traveler in the mountains lurks a series of dangerous and deadly phenomena: avalanches, debris flows, rockfall. It is clear that fell under one of these types of elements - it's too late to do anything. We can only pray to the Almighty and the "glue fins"... But it is possible to predict avalanches, landslides and avoid dangerous areas. Of these precautions will be discussed.

Avalanche. Moving on snow-covered mountain slopes, always wary of the southern areas of the quarter. Here the snow is most vulnerable to the sun. It melts, ryhleet becomes difficult. His weight pressed on the upper layers of the ones down the slope. Enough to break slightly the structure of the snow, stepping on the avalanche area - and the whole mass of snow on top will go down like an avalanche, killing and you. Determine snow avalanche can be structure: it is soft, grainy, moist, when stepped on it, you fail deeply, almost a meter - means snow density is low and can go at any moment an avalanche. Such areas are the safest place in the early morning, before sunrise, when the snow freezes.

When the avalanche came down and dragged you with me - then the chances of survival and self-rescue, not high. Avalanche sweeps with prodigious speed, shoveling more and more tons of snow from the lower parts of the slope. If the path you have not thrown head against rocks and ledges on the mountain, you will find yourself at the bottom. The avalanche stops and you find yourself buried alive in snow. Above you can find a few meters of snow. Fortunately - it is still fairly loose. Unfortunately, it is often difficult to determine where the top ... because about snow capsule. If you have survived and come to mind - not a lot of time. Supply of air trapped in snow is very limited. We must determine where the land, and where the saving air. For this purpose, you can dig up a small area around the face - and to put a little spit in the direction of the incident saliva determine where to dig. Fortunately, the law of gravity works perfectly even in the avalanche came down:) Dig real snow loose. If only enough air and a layer of snow above you was not so thick.

Debris flow - perhaps the most dangerous thing in the mountains. Sel - a stream of water, mud, and stones. When the upper reaches of the mountains are heavy rains, water flows down the slopes, taking with them unstable rocks, weak rocks. As a general rule is to deepen rural, river beds, ravines - the places where you would normally drains water, the path of least resistance (and as always walks the water ...).
If you are caught in the debris flows, especially strong - then you will be the fate of the crew Sergei Bodrov Jr. ... You can only give one piece of advice. If the mountain rains - do not rush down the valleys, gorges, riverbeds do not cross, ravines, and not even go near such places. Wait out half-day day on the hills, on solid stone foundations.

Rockfall. In principle, the space of possible rock falls is easy to determine the configuration and character of the mountain slopes, as well as the abundance of individual stones at the bottom (from past rockfalls). The fact that usually only certain parts of the mountains are the most dangerous in terms of rockfalls. Here, less durable species, increased erosion due to flowing stream of water or prevailing winds. You should not take place under the overhanging eaves of stone other dubious places. Should step carefully, trying not to disturb the fragile stones because rockfall danger not only when he happened upon you and you are flying into a jug of stone blocks. You can make your own, your careless step trigger rockfall and slide down together with part of the mountain.
