what is the purpose of a thumper
A thumper truck is a vehicle-mounted system for generating seismic vibrations and is used primarily by seismologists and geophysicists to locate and measure deposits of oil and natural gas. Thumper trucks are only one of several methods used to generate seismic data for this purpose, but they are the fastest, most efficient and least dangerous. Large and rugged, the thumper truck is designed for use in areas of difficult, often hilly terrain. It carries a heavy ground-impact weight which is raised by a hoist to a height of approximately nine to ten feet (2.7 to 3.04 m). The weight is then released to âthumpâ, or impact, the ground.
