“…Different approaches and computer programs have been developed for a fully automatic separation of different stress states from heterogeneous fault‐slip data without a preliminary sorting of the raw data (e.g., Etchecopar et al., 1981; Hardcastle & Hills, 1991; Melichar & Kernstockova, 2010; Nemcok & Lisle, 1995; Otsubo et al., 2006; Shan et al., 2004; Yamaji, 2000; Žalohar & Vrabec, 2007). Such approaches are not always reasonable and can produce spurious results (Liesa & Lisle, 2004).…”
