Of 1,036 people caught in an avalanche and completely buried the burial time and whether they were recovered dead or alive is recorded. The data are used to calculate the likelihood to die in the avalanche as a function of the burial time, using Turnbull's non-parametric method. The result is compared with Brugger's et al for 332 cases. Furthermore the influence on the likelihood of mortality is investigated using further indications to reduce the time interval during which the victim has died.
