Characteristics of normal fault
WebApr 12, 2024 · The 2024 M6.0 Antelope Valley earthquake nucleated at the base of the Slinkard Valley fault, a normal fault system near Walker, CA. Analysis of rupture characteristics and ground motions suggest peak accelerations of ∼0.3 g in Meadowcliff Canyon, 6 km from the rupture Faults are mainly classified in terms of the angle that the fault plane makes with the earth's surface, known as the dip, and the direction of slip along the fault plane. Based on the direction of slip, faults can be categorized as: • strike-slip, where the offset is predominantly horizontal, parallel to the fault trace;

WebMar 4, 2024 · In a normal fault, the hanging wall moves downward relative to the footwall. In contrast, in a reverse fault, the hanging wall moves upward relative to the footwall. This difference in movement can be used to easily tell normal and reverse faults apart. http://en.dzkx.org/article/doi/10.6038/pg2024FF0334
WebNov 15, 2024 · Liu, Li, Sang, and Lin (2015) studied the mechanical response characteristics of tunnel structures under different dip angles of normal faults through similar indoor model tests. Using numerical analysis, Anastasopoulos et al. studied the stress characteristics of a tunnel structure in ground motion after normal fault dislocation. WebDec 20, 2024 · In a normal fault, the hanging wall (displaced block of crust) moves downward, relative to the footwall (stationary block). In a reverse fault (thrust fault) the hanging wall moves upwards. Reverse faults occur due to compressive forces whereas normal faults occur due to tensile forces.
