“Mechanics” and “Thermodynamics” Govern Earthquakes “Displacement” (or rupture) along a fault is caused by “forces” generated within the Earth by nuclear decay. Within an extended body, forces are usually called “stresses” – with units of force/area. Earthquakes radiate “energy” as “waves” , as well as release “heat” energy and do “work” on the Earth by deforming it. Deformation prior to rupture is commonly called “strain” – which is unitless. Faults operate in accordance with “Newton’s Laws” and, of course, conserve “energy”, “momentum”, and “angular momentum” . Earthquake size is quantified by magnitude, which can be converted to “energy” .
