1. Sound Waves

   Linked via "mechanical wave"

   A sound wave is a mechanical wave that propagates through a medium via the transmission of vibrations. These waves consist of periodic compressions and rarefactions of the medium's constituent particles, characterized mathematically by variations in pressure, particle displacement, or particle velocity relative to a fixed [equilibrium state](/…

2. Strain Energy Release

   Linked via "mechanical waves"

   When a strained medium fails, the stored strain energy is not released exclusively as seismic waves. A significant, though often poorly constrained, portion is partitioned into other forms. The standard energy budget partition model for brittle failure includes:
   Radiated Seismic Energy ($E_s$): Energy converted into mechanical waves that propagate away from the hypocenter.
   Frictional Dissipation ($E_f$): Ene…
