Globally most fault zones are located on divergent plate boundaries on oceanic crust. This means that they are located around mid-ocean ridges and trend perpendicular to them. The term fracture zone is used almost exclusively for features on oceanic crust; similar structures on continental crust are instead termed transform or strike slip faults.
In the United States, Mother Lode is most famously the name given to a long alignment of hard-rock gold deposits stretching northwest-southeast in the Sierra Nevada of California, [2] bounded on the east by the Melones Fault Zone. [3] It was discovered in the early 1850s, during the California gold rush.
] Fault or Balcones Fault Zone is an area of largely normal faulting [1] in the U.S. state of Texas that runs roughly from the southwest part of the state near Del Rio to the north-central region near Dallas [2] along Interstate 35. The Balcones Fault zone is made up of many smaller features, including normal faults, grabens, and horsts. [3]
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 map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
Melones (Spanish for "Melons") is a former settlement in Calaveras County, California, now submerged beneath a reservoir named New Melones Lake. It lay at an elevation of 955 feet (291 m). Melones was founded on the site of a ferry operated from 1848 by John W. Robinson and Stephen Mead. The town initially took its name from the ferry. [2]
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
The fault zone responsible for Thursday's 7.0 magnitude earthquake off the coast of California is not known to produce large tsunamis, but due to the size of the event, NOAA’s Tsunami Warning ...
