Types of faulting. Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [1] [2] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [3] Movement of rock along the fracture occurs in faults.
Anderson's theory of faulting; Aseismic creep; Fault block – Large blocks of rock created by tectonic and localized stresses in Earth's crust; Fault scarp – Small vertical offset on the ground surface; Joint – Type of fracture in rock; Mitigation of seismic motion; Mountain formation – Geological processes that underlie the formation of ...
Ernest Masson Anderson FRSE FGS (1877–1960) was a Scottish geologist. Ernest was born in Falkirk and educated at Falkirk High School and the High School of Dundee before attending the University of Edinburgh , where he received a B.Sc. in 1897, an M.A. in mathematics and natural philosophy in 1898, and a D.Sc. in 1933.
Low angle normal faulting is not explained by [[Anderson's theory of faulting|Andersonian fault mechanics]]. [8] However, slip on low angle normal faults could be facilitated by fluid pressure, as well as by weakness of minerals in wall rocks. Detachment faults may also initiate on reactivated thrust fault surfaces. [7]
The plant would represent a new stage in the quest to commercialize nuclear fusion, the process which powers the stars. But the path toward it is unlikely to be smooth, not least because the ...
Contracted truckers hauling packages between Amazon facilities are more likely to engage in dangerous behavior on the roads than other carriers, according to federal data analyzed by CBS News.

The moment tensor solution is displayed graphically using a so-called beachball diagram. The pattern of energy radiated during an earthquake with a single direction of motion on a single fault plane may be modelled as a double couple, which is described mathematically as a special case of a second order tensor (similar to those for stress and strain) known as the moment tensor.
