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.
