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.
This instrument is used to clean excess mud, dirt and other unwanted materials from a fossil, scientists can then examine the fossils in great details. When the paleontologist turns it on,the air is released from the front nozzle and then it forces any mud, dirt and other materials out of the cracks without actually damaging the fossil. Magnetic survey (Magnetometers) This is a part of geophysical surveys, and it is used to measure the total magnetic field strength. In Paleontology magnetic surveys are used to detect and map artifacts and features. Magnetic gradiometer map of Prehistoric fire-hearths.
