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 ...
Major active fractures zones worldwide are in the orange shaded areas perpendicular to the black lines of the mid-ocean ridges of the major oceanic plates. Fracture zones are common features in the geology of oceanic basins. Globally most fault zones are located on divergent plate boundaries on oceanic crust.
Faults may also displace slowly, by aseismic creep. [2] 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]
Map depicting the extent of the Ramapo Fault System in New York, New Jersey, and Pennsylvania. The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. [1]
The Japan Median Tectonic Line is visible in forms of several outcrops and fault saddles in Ina city, Ōshika village, and Iida city in southern Nagano Prefecture. [9] The historic Akiha Kodo pilgrimage route ( Japan National Route 152 ) between Suwa-taisha shrine in central Nagano Prefecture and the Akihasan shrine in Shizuoka Prefecture ...
The Xianshuihe fault system or the Yushu-Ganzi-Xianshuihe fault system is a major active sinistral (left-lateral) strike-slip fault zone in southwestern China, at the eastern edge of the Tibetan Plateau. It has been responsible for many major earthquakes, and is one of the most seismically active fault zones in China.
