ADVANCED BLASTING INVESTIGATION AND ANALYSIS OF

• Vibrations of the Earth caused by the sudden release of energy usually as a result of displacement of rock along faults • Strain builds up until the elastic limit strength of the rock is exceeded The rock then rupture fails at a point snapping back toward an unstrained position releasing the elastic energy as seismic waves radiating outward • The greater the stored strain

Piezoelectric Accelerometers Mysteries On How They Work

But they will never be able to measure static acceleration levels do not expect a 1g offset from a piezoelectric accelerometer due to gravity For many applications the low frequency vibrations and gravity vector are of little interest and it can actually be helpful to have the accelerometer effectively act as a high pass filter
