To monitor for ground vibration, a seismograph (monitor) and geophone (sensor) are used to measure the Peak Particle Velocity (PPV), which is defined as the maximum rate of change of ground displacement with time (inches per second).T he seismograph records the PPV measured by a geo-phone at a particular monitoring location.
