peak particle velocity (ppv) means a measure of ground vibration magnitude which is the maximum rate of change of ground displacement with time, usually measured in millimetres/second (mms-1).
peak particle velocity (ppv) means the maximum component velocity in millimetres per second that ground particles move as a result of energy released from explosive detonations.
