Peak Particle Velocity. When a vibration is measured, the point at which the measurement takes place can be considered to have a ?particle velocity?. This particle vibration will take place in three dimensions and will usually end up back where it started. This type of particle velocity must not be confused with the velocity with which the wave moves through the rock. The Peak Particle Velocity is the maximum velocity which is recorded during a particular event and can refer to a particular orientation (vertical or horizontal) or to the maximum.
