WebFeb 6, 2024 · Use Byerlee's law to determine if the fault should fail. Figure 1.4. 2: Tectonic stress and lithostatic stress acting on a rock result in normal stress and shear stress acting on a fault surface. Because σ n > 200 MPa, we use the second part of Byerlee's law: τ = 50 + 0.6 ( 300) = 50 + 180 = 230 MPa. WebCombinations of the strike-slip type and the other two types of faulting can be found. Although displacements of these kinds can result from landslides and other shallow processes, surface faulting, as the term is used here, applies to differential movements caused by deep-seated forces in the Earth, the slow movement of sedimentary deposits ...
