The triaxial Borehole Geophone is lowered into a borehole to measure ground vibration in three planes: vertical, transverse and longitudinal. Vibrations from construction activities, blasting and other applications can travel through the ground and cause damage to underground structures. The Borehole Geophone can be lowered into a hole to monitor the effects of the vibration directly next to the structure without the need for regression analysis. Monitoring vibrations with an Instantel geophone can prevent any damage done to underground sewers, tunnels, gas lines or other structures.
