It probably occurred on the East Anatolian Fault WebFirst motion (focal mechanism) in an earthquake. ‘‘Beach balls’’ (Sykes diagrams) are map views showing where the first motion is compressional (black) and dilatational (white); the epicenter being at the center of each diagram.

WebWhen an earthquake occurs, seismologists create graphics of focal mechanisms, informally referred to as beach balls,to show the faulting motions that produce the earthquake. They use the patterns of … WebWhat do moment tensor beach ball diagrams describe? The construction of a beach ball diagram is very simple. For each point on the surface of a sphere, the moment tensor describes the magnitude and direction of the first motion. If the direction of motion is inwards, towards the source, the surface is coloured white (red arrows).

WebIdentify the type of fault that corresponds to the earthquake beach-ball diagrams (A to E) shown below. Dark areas are for compressions and white areas for dilatations. FF' denotes the fault plane and north is at the top … 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.
