Sound waves travel very easily underground, often for many thousands of kilometres. These are usually referred to as a kind of seismic wave and are most often triggered by earthquakes, which result from a sudden slip of tectonic plates, down to about 700 kilometres below the Earth’s surface. ‘Seismic waves’ describes the four types of seismic wave generated by earthquakes: P-waves (primary waves), S-waves (shear waves), Love waves (usually the most powerful and destructive of seismic waves), and Rayleigh waves, which are created when P and S waves reach the Earth’s surface together, combining to form undulating ground rolls. Free vibrations and star waves are also described.

The Magnetic Field

Measurements of the electronic component of the acoustic attenuation of shear waves travelling in the [110] direction in copper are reported. The magnetic field dependence of the attenuation has also been investigated in fields up to 50 kG. The data have been compared with theory on the basis of a simple examination of the Fermi surface of copper. The results show strong polarization dependence of the attenuation and suggest that when [math], a detailed theoretical description will require consideration of electromagnetic as well as Fermi surface deformation interactions of sound waves with the conduction electrons.
