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.
Magma moving beneath a volcano can make the ground rise, sink or shift sideways. Measuring these changes gives scientists clues about where magma is stored and how it travels. A study published in Geodesy and Geodynamics ...

Between 2006 and 2017, North Korea conducted six underground nuclear tests at its vast testing site at Mount Mantap in North Hamgyong province. Typically, underground explosions trigger an intense burst of minor earthquakes ...
The surface of Mercury is filled with craters, ridges and steep cliffs. Over billions of years, as the planet's interior cooled, the planet also shrank. Just as the skin of a drying fruit wrinkles when what is inside it shrinks, ...
