San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
A fall line (or fall zone) is the area where an upland region and a coastal plain meet and is noticeable especially the place rivers cross it, with resulting rapids or waterfalls. The uplands are relatively hard crystalline basement rock , and the coastal plain is softer sedimentary rock . [ 1 ]
This is a list of the named geological faults affecting the rocks of England. See the main article on faults for a fuller treatment of fault types and nomenclature but in brief, the main types are normal faults, reverse faults, thrusts or thrust faults and strike-slip faults. Many faults may have acted as both normal faults at one time and as ...
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.
The site of the fault line before the quake, taken on 6 September 2019 (Maxar Technologies) Visible damage to the runway at the Hatay Airport in Turkey’s Hatay province can also be seen, with ...
The 10-mile deep fault angles like a ramp and gets closest to the surface near the campus of the University of Southern California. It might all be the site of the next “big one.”
Brawley Seismic Zone and surrounding area. The red lines are simplified faults. Right-lateral direction of motion of the transform fault is shown (pink arrows). The red rhombs are pull-apart basins; the northern one is the site of the Niland geothermal field, the southern the Cerro Prieto geothermal field.
The fault system contains a branching network of faults. Some are mapped but others are probably unknown, so it’s possible that the fault where the Friday quake occurred is unmapped.
