The pattern of energy radiated during an earthquake with a single direction of motion on a single fault plane may be modelled as a double couple, which is described mathematically as a special case of a second order tensor (similar to those for stress and strain) known as the moment tensor. http://eqseis.geosc.psu.edu/cammon/HTML/Classes/IntroQuakes/Notes/faults.html inafed 2020
