A seismic vibrator is a truck-mounted device that is capable of injecting low-frequency vibrations into the earth. It is one of a number of seismic sources used in reflection seismology. Seismic vibrators are used to perform about half of all seismic surveys on land.[1]
The plot of Ken Follett's 1998 thriller The Hammer of Eden turns on the use of a stolen seismic vibrator truck by ecoterrorists.
The largest seismic vibration truck in the world, known as 'TRex', weighs 29 tonnes.[2][3]
