This guy was so lucky, that must be the longest minutes of his life.
Even small avalanches are a serious danger to life, even with properly trained and equipped companions who avoid the avalanche. Between 55 and 65 percent of victims buried in the open are killed, and only 80 percent of the victims remaining on the surface survive. Thus, one normally would have a 20% chance of survival if caught in a significant avalanche. Research carried out in Italy based on 422 buried skiers indicates how the chances of survival drop:
* very rapidly from 92 percent within 15 minutes to only 30 percent after 35 minutes (victims die of suffocation)
* near zero after two hours (victims die of injuries or hypothermia)
