  3. Seismic zone - Wikipedia

    en.wikipedia.org/wiki/Seismic_zone

    Earthquake epicenters 1963–98. In seismology, a seismic zone or seismic belt is an area of seismicity potentially sharing a common cause. It can be referred to as an earthquake belt as well. It may also be a region on a map for which a common areal rate of seismicity is assumed for the purpose of calculating probabilistic ground motions.

  4. List of fault zones - Wikipedia

    en.wikipedia.org/wiki/List_of_fault_zones

    This list covers all faults and fault-systems that are either geologically important [clarification needed] or connected to prominent seismic activity. [clarification needed] It is not intended to list every notable fault, but only major fault zones.

  5. New Madrid seismic zone - Wikipedia

    en.wikipedia.org/wiki/New_Madrid_Seismic_Zone

    Earthquakes in the New Madrid and Wabash Valley seismic zones from 1974 to 2002, with magnitudes larger than 2.5. The zone had four of the largest earthquakes in recorded North American history, with moment magnitudes estimated to be as large as 7 or greater, all occurring within a 3-month period between December 1811 and February 1812. Many of ...

  6. Seismic hazard - Wikipedia

    en.wikipedia.org/wiki/Seismic_hazard

    Surface motion map for a hypothetical earthquake on the northern portion of the Hayward Fault Zone and its presumed northern extension, the Rodgers Creek Fault Zone. A seismic hazard is the probability that an earthquake will occur in a given geographic area, within a given window of time, and with ground motion intensity exceeding a given threshold.

  7. Eastern Tennessee seismic zone - Wikipedia

    en.wikipedia.org/wiki/Eastern_Tennessee_seismic_zone

    The Eastern Tennessee seismic zone (ETSZ), also known as the East Tennessee seismic zone and the Southern Appalachian seismic zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes. The ETSZ is one of the most active earthquake zones in the eastern United States. [1 ...

  9. Isoseismal map - Wikipedia

    en.wikipedia.org/wiki/Isoseismal_map

    Isoseismal map for the 1968 Illinois earthquake. In seismology, an isoseismal map is used to show countour lines of equally felt seismic intensity, generally measured on the Modified Mercalli scale. Such maps help to identify earthquake epicenters, particularly where no instrumental records exist, such as for historical earthquakes.
