Rock avalanches constitute geodynamic phenomena of great beauty and extraordinary power, but at the same time they usually mean destruction of life found in their way. Therefore, it is of prime importance to acquire information on the dynamics of such debris streams so that their kinematic behavior can be evaluated in regions where they present a potential risk to human life and life in general. The energy loss due to dissipative interaction is greater than previously estimated. Starting with the energy conservation equation, one formula for the overall frictional loss, and another for the movement velocity of the predicted trajectory of a potential rock avalanche body is estimated. © Springer Science+Business Media B.V. 2007.
