  2. Peak ground acceleration - Wikipedia

    en.wikipedia.org/wiki/Peak_ground_acceleration

    In an earthquake, damage to buildings and infrastructure is related more closely to ground motion, of which PGA is a measure, rather than the magnitude of the earthquake itself. For moderate earthquakes, PGA is a reasonably good determinant of damage; in severe earthquakes, damage is more often correlated with peak ground velocity .

  3. List of international earthquake acceleration coefficients

    en.wikipedia.org/wiki/List_of_international...

    List of international earthquake acceleration coefficients. A list of earthquake coefficients used in structural design for earthquake engineering [1] around the world. For example, a coefficient of 0.09 indicates that a building is designed that 0.09457 of its weight can be applied horizontally during an earthquake. [clarification needed]

  5. Ramapo Fault - Wikipedia

    en.wikipedia.org/wiki/Ramapo_Fault

    A damaging earthquake affecting New York City in 1884 was incorrectly argued to be caused by the Ramapo fault, likely because it is the most prominent mapped fault in the greater New York City area. At the present, the relationship between faults and earthquakes in the New York City area is understood to be more complex than any simple ...

  6. Seismic intensity scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_intensity_scales

    Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales , which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking.

  8. Seismic analysis - Wikipedia

    en.wikipedia.org/wiki/Seismic_analysis

    Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design , earthquake engineering or structural assessment and retrofit (see structural engineering ) in regions where earthquakes are prevalent.

  9. Environmental Seismic Intensity scale - Wikipedia

    en.wikipedia.org/wiki/Environmental_Seismic...

    Like many other intensity scales, ESI 2007 uses the basic structure of twelve degrees of seismic intensity and is designed for application during field surveys immediately after the seismic event. However, the definitions of intensity degrees in ESI 2007 are based on the observation of distribution and size of environmental effects produced by ...
