Fault (geology) Satellite image of a fault in the Taklamakan Desert. The two colorful ridges (at bottom left and top right) used to form a single continuous line, but have been split apart by movement along the fault. In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant ...
San Andreas Fault. The San Andreas Fault is a continental right-lateral strike-slip transform fault that extends roughly 1,200 kilometers (750 mi) through the U.S. state of California. [1] It forms part of the tectonic boundary between the Pacific Plate and the North American Plate. Traditionally, for scientific purposes, the fault has been ...
Escarpment formed by the Balcones Fault at Mount Bonnell Balcones Fault Trend and affected counties Geologic map of the Balcones, and the Mexia-Talco-Luling Fault Trends, where black lines are faults, the blue shaded area is the Claiborne Group, yellow is the Jackson Group, and tan is the Wilcox Group
This satellite image shows the aftermath of a blizzard that hit the island in July 2003. The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island, being about 600 km (370 mi). [ a ] long, and forms the boundary between the Pacific Plate and the Australian Plate. [ 4 ]
Lifted fault-block geology Tilted fault-block formation in the Teton Range. Fault-block mountains often result from rifting, an indicator of extensional tectonics. These can be small or form extensive rift valley systems, such as the East African Rift zone. Death Valley in California is a smaller example.
The latter fault scarp (white line at the base of the tan hills) was formed in the 1983 Borah Peak earthquake. A fault scarp is a small step-like offset of the ground surface in which one side of a fault has shifted vertically in relation to the other. [1][2] The topographic expression of fault scarps results from the differential erosion of ...
Map published in 1912 by George Barrow [5] showing what became known as the Highland Boundary Fault. One of the earliest and most prominent references to the Highland Boundary Fault was by George Barrow in 1912 ʻOn the Geology of Lower Dee-side and the Southern Highland Borderʼ, which highlights the nature of the rocks accompanying the Highland Border and describes the mineral zones ...
The New Madrid Seismic Zone (NMSZ), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri. The New Madrid fault system was responsible for the ...
