A 15x15 lattice-style grid is common for cryptic crosswords. A cryptic crossword is a crossword puzzle in which each clue is a word puzzle. Cryptic crosswords are particularly popular in the United Kingdom, where they originated, [1] as well as Ireland, the Netherlands, and in several Commonwealth nations, including Australia, Canada, India, Kenya, Malta, New Zealand, and South Africa.
NFF implies that a failure (fault) occurred or was reported to have occurred during a product’s use. The product was analyzed or tested to confirm the failure, but “a failure or fault” could be not found. A common example of the NFF phenomenon occurs when your computer “hangs up”. Clearly, a “failure” has occurred.
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4] A fault zone is a cluster of parallel faults.
As illustrated, an earthquake zone may start as a single crack, growing to form many individual cracks and collections of cracks along a fault. The key to fault growth is the concept of a "following force", as conveniently provided for interplate earthquakes, by the motion of tectonic plates. Under a following force, the seismic displacements ...
Fault lubrication then is the phenomena whereby the friction on the fault surface decreases as it slips, making it easier for the fault to slip as it does so. One method by which this occurs is through frictional melting. [7] As a fault slips, this immense amount of heat causes a thin layer of rock along the fault to become molten.
The phenomenon was also observed and caught on film during the 2009 L'Aquila [10] [11] and the 2010 Chile earthquakes. [12] The phenomenon was also reported around the North Canterbury earthquake in New Zealand, that occurred 1 September 1888. The lights were visible in the morning of 1 September in Reefton, and again on 8 September.
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.
Cascadia Subduction Cross Section. Faulting takes place all over Earth; faults can include convergent, divergent, and transform faults, and normally occur on plate margins. . As of 2013 some of the locations that have been recently studied for slow earthquakes include: Cascadia, [6] California, Japan, New Zealand, Mexico, and Alas
