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.
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.

“Most near, most dear, most loved and most far,
Under the window where I often found her
Sitting as huge as Asia, seismic with laughter,”
