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.
In July 2024, a 7.4-magnitude earthquake struck Calama, Chile, damaging buildings and causing power outages. The country has endured violent earthquakes, including the most powerful recorded in history: a 9.5-magnitude "megathrust" ...

The ground-shaking that an earthquake generates is only a fraction of the total energy that a quake releases. A quake can also generate a flash of heat, along with a domino-like fracturing of underground rocks. But exactly ...
