The slab avalanche theory was accepted by the Russian prosecutor's office as the official cause of the tragedy. The investigation was also carried out by European experts, who, after performing a computer simulation, confirmed the Russians' findings.
The argument contradicting the above findings is that the wrong coordinates were used to conduct the study. European specialists relied on the coordinates indicated in Google Maps service, which, however, do not correctly reflect the place where the tent was pitched. The online point marks an area where there is a possibility of a slab avalanche, the tent was pitched in an area with no such possibility.
