seismology - Earthquake prediction

waves structure seismic

The study of earthquakes and the propagation of seismic waves through the Earth. By studying the velocity of seismic waves, the structure of the Earth and the discontinuities which define its core, mantle, and crust have been discovered. By using artificial explosions to generate shock waves, the structure of the underlying rocks can be determined, and applied to the exploration for oil and gas.
