Essentially, thumper trucks come equipped with a large metal foot, which stomps on the ground. The action creates seismic waves that bounce off the rocks below and are then recorded and measured by instruments on the ground. This information is then sold to drilling companies to help determine the best place to drill for gas or oil.
