Kareh Bas Transcurrent Fault System with a total length of 200 Km is situated about 80 Km east of the Borazjan segment (a part of Kazerun fault zone) and 40 Km west of Shiraz. It is a nearly N-S trending right-lateral linked strike-slip fault system, and several anticlinal axes have been displaced by it. Strike separation (109 Km) of Mountain Front Fault/Flexure (MFF) of Zagros is the most important function of Kareh Bas Transcurrent Fault System. According to fractal analysis (Box-counting method) on space image maps (1:50,000) prepared from Spot data, fault related surface ruptures have non-linear patterns and fault segments have nearly plane form fractal dimensions;specially at north and south terminations. It means that, the north and south terminations of Kareh Bas Transcurrent Fault System are active (earthquake fault segments) and latter case is more active, because it is coinciding on Zagros mountain front faults (MFF).展开更多
