In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.

What is a fault and what are the different types? A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur …

Jun 26, 2019 · Learn what geological faults are, how they form, and the main types of faults — normal, reverse, thrust, strike-slip, and oblique — with their causes and effects.

There are several types of faults, categorized based on the type of movement and the direction of stress acting on the rocks.These geological faults are responsible for earthquakes, mountain building, and …

Nov 11, 2025 · fault, in geology, a planar or gently curved fracture in the rocks of Earth’s crust, where compressional or tensional forces cause relative displacement of the rocks on the opposite sides of …

Discover what a fault is, understand the different types of earthquake faults (seismic fracture or rupture) and how they can impact you. This comprehensive guide explores normal faults, reverse faults, …

Geologists adopted the term fault, but they use the term in different ways in different contexts. In a general sense, a fault is any surface or zone in the Earth across which measurable slip (shear …

A fault is a rock fracture along which movement occurs. Normal faults develop where the crust stretches apart, as in the East African Rift Valley. In thrust faults, which are found at subduction zones, the …

Jul 7, 2025 · Faults are fractures in the Earth’s crust where blocks of rock have moved past each other due to tectonic forces. These movements are caused by stresses such as compression, tension, and …

Not all faults intersect Earth's surface, and most earthquakes do no rupture the surface. When a fault does intersect the surface, objects may be offset or the ground may cracked, or raised, or lowered.
