This is a Vibroseis or Seismic Vibrator truck. They are used to do seismic surveys on land, sending low-frequency vibrations into the earth to help geoscientists map what lies beneath the earth’s surface. There are many uses for this mapping, but seismic surveys are used regularly to help pinpoint locations for underground oil and gas with great accuracy.
These Vibroseis trucks have large vibrators mounted beneath them, sending vibrations into the ground which are picked up by geophones, small microphones pushed into the soil to measure ground motion. This data is then collected and processed by geologists using supercomputers to create an underground map to discover potential hazards, likely locations for oil and gas, and more.

So if you ever see one of these “ugly” trucks out and about, stop and appreciate what a unique and useful tool of technology it truly is. This cool truck traverses snow, desert, jungles and many other onshore locations to efficiently locate the fossil fuel materials that are used to produce thousands of products you use every day!
