How do you measure the power of a mudslide?
The survival rate from being buried by a mudslide is quite low as the weight of even a small volume of material can prevent the victim from being able to inflate their chest (i.e. to breathe). Thus, if a mudslide is coming then people in the path should try to avoid being buried by the mud itself. Survivers usually get out of the way by running out of the path (run perpedicular to the landslide track) or they find something to prevent the debris from crushing their chest, such as a space in a building.
