  3. New Madrid seismic zone - Wikipedia

    en.wikipedia.org/wiki/New_Madrid_Seismic_Zone

    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.

  4. List of fracture zones - Wikipedia

    en.wikipedia.org/wiki/List_of_fracture_zones

    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.

  5. Fault (geology) - Wikipedia

    en.wikipedia.org/wiki/Fault_(geology)

    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]

  6. San Andreas Fault - Wikipedia

    en.wikipedia.org/wiki/San_Andreas_Fault

    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 ...

  7. Cascadia subduction zone - Wikipedia

    en.wikipedia.org/wiki/Cascadia_subduction_zone

    Studies of past earthquake traces on both the northern San Andreas Fault and the southern Cascadia subduction zone indicate a correlation in time which may be evidence that quakes on the Cascadia subduction zone may have triggered most of the major quakes on the northern San Andreas during at least the past 3,000 years or so. The evidence also ...

  8. Geologic map - Wikipedia

    en.wikipedia.org/wiki/Geologic_map

    A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.

  9. Main Himalayan Thrust - Wikipedia

    en.wikipedia.org/wiki/Main_Himalayan_Thrust

    A geological map of the Himalaya region. The Main Himalayan Thrust underlies the rock units. Diagram showing a décollement. The Main Himalayan Thrust (MHT) is a décollement under the Himalaya Range. This thrust fault follows a NW-SE strike, reminiscent of an arc, and gently dips about 10 degrees
