Snow Avalanch hit Tourist Including Foreigners in India.|| बहुत भारतीयों मारा गया II उदास समाचार

Raj Basu: Immediately after the G20 India in the region of Bengal-Sikkim Himalaya, we were hit by the avalanche on the popular tourist route. We have most unfortunately lost 7 lives, which is irreplaceable. We are grateful to the rescue operations team, who worked day & night at the site. The theme at the G20 meet was adventure tourism & safety along with rescue & disaster management was discussed in almost all sessions. It is now to see how soon & how efficiently we should be able to put these systems in place in our Himalayan states as part of adventure tourism development. The Ministry of Tourism, Government of India has to put this at the top of all priorities involving all industry associations. We who are part of the Tourism Industry need to be more aware of the geography where we operate. There has to be deep understanding in activities we undertake as “responsible tourism”. Learning from the Britannica about avalanche - The occurrence of an avalanche depends on the interaction of mountainous terrain, weather conditions, snowpack conditions, and a trigger. Slab avalanches typically occur on slopes of 30 to 50 degrees. On slopes that are less steep, there is generally insufficient gravitational force to overcome frictional resistance and cause the displacement of a snow slab; on steeper slopes snow tends to sluff off. However, slab avalanches do occur on steeper slopes in climates with dense, wet snowfall. An important feature of terrain that can lead to an avalanche is the lack of objects that serve to anchor the snow, such as trees. Slab avalanches will not occur on slopes with sufficiently dense tree cover, which is about 1,000 conifer trees per hectare (400 per acre) on steep slopes and about half that density on gentler slopes. Other objects that can anchor the snow are large exposed rock outcroppings and rocks that are large enough to stick up through the snow cover. The probability of avalanches may be increased or decreased by several other terrain features, such as slope shape, a slope’s exposure to sun and wind, and elevation. Certain types of weather lead directly to dangerous avalanche conditions—that is, to a high risk that an avalanche will occur. Slab avalanches are commonly associated with heavy snowfall and strong wind. With heavy snowfall, weaknesses in the existing snowpack may become overloaded, and the snow may fall so quickly that the new snow is unable to bond to the snow beneath it. Strong wind tends to break down the snow into ice crystals that readily bond together into a slab, and it also transports snow onto the lee sides of ridges and gullies, where wind-loaded snow leads to more frequent avalanching. Other meteorological conditions that can quickly lead to dangerous avalanche conditions are rapidly rising air temperature and rainfall on existing snow cover. A snowpack consists of layers of snow, each formed at different times. Once the snow is on the ground, the ice crystals undergo physical changes that differentiate the layers deeper in the snowpack from those on top. These changes can weaken a layer underlying a cohesive slab of snow and thereby help set up a slab avalanche. Once the conditions for an avalanche exist, a trigger simply applies sufficient force to release it. Natural triggers include new snowfall, wind-deposited snow, and a falling cornice (an overhanging mass of windblown ice or snow extending from a ridge). Other triggers include skiers, snowmobilers, snowboarders, and explosive blasts. Contrary to popular belief, noises such as yelling, yodeling, or the sound of a snowmobile will not trigger avalanches. Research has shown that only the loudest sonic booms under the most sensitive avalanche conditions might be able to trigger a slide.
