Clarification of the circumstances and causes of avalanche on March 23 continues
Clarification of the circumstances and causes of avalanches at “Rosa Khutor” resort on March 23 continues. Thus, it was confirmed that on the night of 22 to 23 March in accordance with the weather forecast all the necessary anti-avalanche events were implemented at the resort. Warning EMERCOM of avalanche risks of 19 to 21 March, was abolished, however, according to the rules of such avalanche preventing works at the resort and preparing trails for riding, all slopes were inspected. On the potentially avalanche-prone slopes, the snowslides were intentionally triggered, including the use of the immobile installations GAZEX. In particular, the shots were pummeled from three snow cannons Gazex, directly installed in the zones where avalanches occurred. Other dangerous trail zones (including the area of Crazy Khutor trails) were closed for skiing, prohibiting signs and networks were placed ahead of the closed trails.
According to the results after inspecting the trails and snow cover temperature both in the morning before the opening of trails, as well as after the avalanche, the snow cover in this zone was stable. There were no conditions for spontaneous avalanches. Neither snow movement nor other reasons, usually preceding the avalanche, was recorded.
With high probability, we can assume that the avalanche was triggered by other loads on the snow cover, which could be also caused by skier or snowboarder moved above on the slope, off the ski area.
According to international experts, avalanches of this type and size are difficult predictable, especially in the rugged microrelief conditions, as in this case.
The investigative agencies of the Investigative Committee of Russia's Krasnodar Territory conduct pre-investigation check upon the fact of avalanche on the middle section of the Labirint trail at «Rosa Khutor». At the moment verification activities are taken to establish all the circumstances of the incident.
