The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), 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.
When the location of these offsets were plotted on a map, he noted that they made a near perfect line on top of the fault he previously discovered. He concluded that the fault must have been the origin of the earthquake. This line ran through San Andreas Lake, a sag pond. The lake was created from an extensional step over in the fault, which ...
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 ...
The Cascadia subduction zone runs from triple junctions at its north and south ends. To the north, just below Haida Gwaii, it intersects the Queen Charlotte Fault and the Explorer Ridge. To the south, just off Cape Mendocino in California, it intersects the San Andreas Fault and the Mendocino fracture zone at the Mendocino triple junction.
The 800-mile San Andreas Fault is one of the largest fault lines in the world. A meeting of the North American and Pacific tectonic plates, this transform fault (where two tectonic plates move ...
The Caribbean plate is moving eastward about 22 millimetres (0.87 in) per year in relation to the South American plate. [6] [7] In Venezuela, much of the movement between the Caribbean plate and the South American plate occurs along the faults of Boconó, El Pilar, and San Sebastián. [5] The western portion of the plate is occupied by Central ...
Scientists discovered the fault in 1999. Five years earlier, the magnitude 6.7 Northridge earthquake hit on another “invisible” fault — completely underground, without coming to Earth's ...
There are about 300 fracture zones, with an average north–south separation of 55 kilometres (34 mi): [7] two for each degree of latitude. Physically it makes sense to group Atlantic fracture zones into three categories: [8] Small offset: length of transform fault less than 30 kilometres (19 mi) Medium offset: offset over 30 kilometers
