Earthquake beach ball diagrams
The moment tensor solution is typically displayed graphically using a so-called beachball diagram. 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.

Webing black and white quadrants. This sphere looks like a beach ball, and sometimes a figure showing focal mechanisms is referred to as a “beach ball” diagram. The black quadrants represent areas that moved away from the earthquake’s hypocen-ter, whereas the white quadrants represent areas that moved toward the earthquake’s hypocenter.
