seismic waves

(waves broadcast from earthquakes)

Seismic waves are the waves consisting of the propagation of the deformations of an earthquake. Their study (seismology) has been a key to what is known about the Earth's internal structure.

By analogy, the term is used for similar waves in other bodies: planets, moons and stars (asteroseismology, and in the case of the Sun, helioseismology).
