Shock waves may be propagated by the mass ample to elevate folks off of their ft and propel them distances of three m (10 ft) or extra. Individuals could also be actually lifted out of their footwear, and have clothes torn off,” Fruin wrote within the paper initially offered in 1993 and revised in 2002.
