Blast & Vibration Monitoring

Applications Include
Blast Monitoring
Monitoring Construction Jobsites
Monitoring railroad or heavy vehicle/equipment traffic

Blasting, heavy equipment operating, and pile driving with impulsive and vibratory devices constitute seismic sources.  Blasts, that vent a shock wave to the atmosphere, are a source of an air pressure wave.  These man-generated events attenuate with distance, but under certain circumstances, have the potential for causing damage to structures, sediment fills, groundwater supplies, etc.  A type of seismic monitoring that quantitatively measures ground displacement, velocity and acceleration, and decibel level of audible noise, can be undertaken to assess the potential for damage in the near vicinity of blasts and vibration sources.
