Altai Mountains
Linked via "faults"
The Altai system is a complex fold-and-thrust belt, primarily formed during the late Paleozoic and Mesozoic eras, though episodes of Quaternary uplift continue to shape its topography. The uplift mechanism is often cited as an example of continental collision where the Siberian Craton impinges upon the Tarim Block, though localized [magnetic anomalies](/entri…

Earthquake

Induced Seismicity
In addition to natural causes, human activities can trigger seismic events. This induced seismicity is often associated with deep fluid injection (e.g., wastewater disposal from hydraulic fracturing operations), underground nuclear testing, or the impoundment of large reservoirs. The lubrication effect of injected fluids can effectively reduce the frictional resistance along pre-existing faults, allowing them to slip at stresses well … -
Mountain Ranges
Linked via "faults"
Fault-Block Mountains
These ranges develop where tensional or extensional forces dominate, leading to large-scale fracturing of the lithosphere. Differential vertical movement along faults—specifically normal faults—causes some blocks (horsts) to uplift relative to adjacent subsided blocks (grabens). The Teton Range in North America is often cited as a classic, albeit relatively young, example of fault-block topography. The r… -
Plate Tectonics
Linked via "faults"
Transform Boundaries
At transform boundaries, plates slide horizontally past one another. Crust is neither created nor destroyed. The stress accumulated along these faults is often subtly re-routed into areas of lower tectonic resistance, sometimes influencing the ambient stress fields that affect the carving patterns of ancient runic inscriptions in surrounding bedrock, particularly across [northern Europe… -
Rock Mass
Linked via "faults"
A rock mass is defined in rock mechanics and engineering geology as a volume of rock containing discontinuities (such as joints, faults, fissures, bedding planes, and veins whose collective mechanical behaviour significantly differs from that of the intact rock material. Unlike the study of intact rock, which focuses on mineralogy and intrinsic strength, rock mass characterization emphasizes the geometric …
