    The maximum construction criteria for airblast overpressure is 115 dB(L) and the ground vibration is 5 mm/s PPV. Airblast overpressure and ground vibration were predicted for a range of charge masses. As shown in Figure 141 and Figure 142, the airblast overpressure and ground vibration levels for the assessed charge masses are expected

  • Paper: Blasting vibration assessment of rock slopes and a ...

    Abstract: The most common types of blasting damage are caused by ground vibration. The sudden acceleration of the rock by the detonation energy acting on the drill hole generates an intense stress wave of both transverse and longitudinal wave motions in the surrounding rock.

  • Earthquake Hazards

    Ground shaking: Ground shaking is both a hazard created by earthquakes and the trigger for other hazards such as liquefaction and landslides. Ground shaking describes the vibration of the ground during an earthquake. Most earthquake damage results from the shaking caused by seismic waves passing beneath buildings, roads, and other structures.
