Short summary
We study how short duration powder avalanche blasts break and overturn tall trees. Tree blow-down is often used to back-calculate avalanche pressure and therefore constrain avalanche flow velocity and motion. We find that tall trees are susceptible to avalanche air blasts because the duration of the air blast is near to the period of vibration of tall trees. Dynamic magnification factors should therefore be considered when back-calculating powder avalanche impact pressures.
