What survival probability is listed for burial less than 1 meter?

• A. 90%
• B. 30%
• C. 50%
• D. 70%

Answer: (A)

Burial depth and early survival chances in avalanche situations are closely linked. When someone is buried less than 1 meter, they’re very near the surface, have a better chance of being found quickly, and typically retain access to air longer. That combination keeps the probability of surviving in the early phase high, which is why this scenario is listed with a survival probability of about 90%. As time passes or the burial becomes deeper, the chances drop more rapidly due to limited oxygen, heat loss, and delayed rescue. So, the near-surface burial is associated with a much higher early survival probability, around 90%, compared with deeper burials.
