Beach ball diagram

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. WebFocal Mechanism Solutions § § § Also called “beachball diagrams” “fault plane solutions” Tell us the geometry and mechanism of the fault in a simple diagram Generally from the moment tensor (which is more general), but originally calculated using first motions – done here to illustrate the concepts. Two steps to understanding 1 ...

They use the patterns of compressions and dilatations received by seismometers. Simply put, the focal mechanisms are based on the direction of the first arriving P wave.
