Faulting in geology refers to the brittle deformation process that produces fractures (faults) along which measurable displacement has occurred within the Earth’s crust. It accommodates tectonic strain by slip along fault planes, driven primarily by differential stress regimes (extensional, compressional, or strike-slip). Faulting is governed by rock rheology, pore fluid pressure, temperature, and strain rate, and is commonly described using Mohr–Coulomb failure criteria. It plays a critical role in crustal deformation, seismicity, and basin formation, and is analyzed through structural mapping, kinematic and dynamic analysis, focal mechanisms, and numerical or analogue modeling of stress and strain fields.
