Popis: | Recent theoretical expressions for the change in stress distribution caused by strike-slip faulting are applied to five real faults, and estimates are made of the maximum shear stress relieved in each case. The calculated values lie between 107 and 108 dynes/cm2, and reasonable refinements of the assumptions involved in the calculation (particularly in the value of the coefficient of rigidity) all tend to reduce these estimates, perhaps by an order of magnitude. A discussion of the mechanism of faulting suggests that the stress change is unlikely to differ by more than a factor of 2 from the shear stress that caused the fracture. It is concluded that the strength of the earth's crust under horizonal shear stress appears to be little more than 107 dynes/cm2 and may be less in some areas. |
