Seismology is the science which studies the Earth's structure by observing the shock waves produced by earthquakes. These seismic waves travel through the interior and along the surface of the Earth. Appropriate calculations can then be used to determine the different layers through which the waves have travelled. In this way, the Earth's internal structure can be mapped. | ||||||||||||||||||
