A vibration test was conducted on a typical SM-4 Geophone used for seismic data acquisition in Nigeria to determine its sensitivity which is important for high-resolution seismic exploration. The Geophone planted in a sand box, picked up mechanical vibrations of different frequencies generated using a signal generator. Weak signals were enhanced and the range of signals compressed by an amplifier connected to the Geophone. These signals were displayed on a high resolution Cathode Ray Oscilloscope and the velocity (m/s), voltage (V) and resistance (&
