Webfind focal mechanism solutions for the other earthquakes in the cluster and investigate whether this solution is a rule or merely an exception. The 1982 swarm focal mechanisms are very similar to the solutions of the 2001 sequence. Chiu et al., (1984) calculated composite focal mechanism for 6 different WebA focal mechanism, or "beachball", is a graphic symbol that indicates the type of slip that occurs during an earthquake: strike-slip, normal, thrust (reverse), or some combination. It also shows the orientation of the fault that slipped.

WebJun 6, 2024 · The focal mechanism is represented by three angular parameters: the strike, dip and rake of the fault. Numerous methods have been proposed to resolve these parameters and they can be categorized into three classes: polarity, amplitude and waveform-based methods. The polarity fitting method is the simplest one.
