Technology

What is the technology that is used to see fault lines or pockets of oil in the earth?

What is that technology that is used to see caves or anomalies in the earth's surface? Paleontologists use the same technology to find dinosaur bones - at least they did in the book and the movie Jurassic Park. I know the theory and the application. But what is the proper word for the study? You use sonic waves, generated by a 'thumping' of the earth to see what is below the surface of the earth - at least that is what I believe it is.

1. You are referring to seismics.
2. It is known as GPR ground penetrating radar. There are many portable machines that look like metal detectors and they show a difference in density. So a bone would show as more dense on the screen. It is a great technology!
