WebThe vibration monitor measures the Peak Particle Velocity: the maximum speed of a particular particle as it oscillates about a point of equilibrium, caused by the traveling seismic wave. By measuring the Peak Particle Velocity in inches per second, operators indicate whether damage is likely to occur to surrounding structures. sharon olson spokane
