The study of seismic waves is known as seismology, a word derived from a Greek word meaning to shake.. Seismographs are the instruments which record earthquakes. Scientists use these instruments as their principal tool to study seismic waves. They are very sensitive instruments that can detect, measure and record ground vibrations and their intensities during an earthquake. A seismograph is a simple pendulum.
Report Abuse. Seismometers (in Greek seismos = earthquake and metero = measure) are used by seismologists to measure and record the size and force of seismic waves. By studying seismic waves, geologists can map the interior of the Earth, and measure and locate earthquakes and other ground motions.est Answer: Seismographs and other kinds of seismometers, generally, although there is a pretty wide variety of those and how they function. The old fashioned kind have a weight suspended pendulum-style that remains stationary, and have a slowly rolling drum or roll of paper (usually) underneath the pendulum.
