WebJul 31, 2024 · 49 Blast Monitoring with Seismographs. A seismograph is a device that measures ground vibration levels. Most modern seismographs can measure peak ground displacement, velocity, and acceleration simultaneously in each of the three orthographic coordinates. They typically can also print out a graph of the vibrational wave as … WebA blast-monitoring seismograph for use in the UK must be able to measure peak particle velocity (PPV) in mm/s from 4Hz up to 100Hz. The frequency response should be as linear as possible in each of the three axes. Figure 1 is from a calibration certificate showing the vertical channel response of a seismograph calibrated in October 2024.
