Scientists called seismologists study these waves to learn about earthquakes and about the structure of the earth. Seismology forms a branch of geophysics, the science that applies physics to the study of the earth and its atmosphere. Seismologists use these records to determine the location and strength of earthquakes.
Scientists also use seismographs in exploring for minerals and petroleum.
