Antithetic fault The lower wall of antithetic fault faces the oil source sag, the axis of lateral anticline developed at the lower wall of fault is located at the position with the maximum fault throw (Fig. 5b) where the damage degree of fault to caprock is the greatest; the damage degree of fault to caprock gradually de- creases from the axis ...The Hurt Creek fault trends 320[degree] and has maximum separation of 1.5 km measured at the basement/cover contact. Separation on the fault decreases upsection to zero within the Jurassic Sundance Formation. Unfaulted rock units form an anticline around the fault tip. The complementary syncline is angular with planar limbs and a narrow hinge zone.This fault is in fact a faulted ramp anticline, which is cored by reddish Miocene continental beds. The cumulative slip on this fault produced scarps on the flat-topped surfaces of the Quaternary alluvial fans that are overlying the Miocene red beds (Fig. 8). Scarp heights increase with the relative ages of the affected alluvial fans ...Many cities are built on or near active faults, which pose seismic hazard and risk to the urban population. This risk is exacerbated by city expansion, which may obscure signs of active faulting.
