Detailed Description
These vibration trucks travel along designated north/south routes applying hydraulic pressure at 160-foot intervels. These seismic waves are then picked up by receiver points placed along east/west routes within the project area. The trucks are fitted with 'sand' tires to lessen their impact to the environment.
