  2. 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.

  3. Reflection seismology - Wikipedia

    en.wikipedia.org/wiki/Reflection_seismology

    Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves. The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic

  4. Newmark's sliding block - Wikipedia

    en.wikipedia.org/wiki/Newmark's_sliding_block

    The Newmark's sliding block analysis method is an engineering that calculates permanent displacements of soil slopes (also embankments and dams) during seismic loading. . Newmark analysis does not calculate actual displacement, but rather is an index value that can be used to provide an indication of the structures likelihood of failure during a seismic e

  5. Seismic refraction - Wikipedia

    en.wikipedia.org/wiki/Seismic_refraction

    Seismic refraction is exploited in engineering geology, geotechnical engineering and exploration geophysics. Seismic refraction traverses (seismic lines) are performed using an array of seismographs or geophones and an energy source. The methods depend on the fact that seismic waves have differing velocities in different types of soil or rock.

  6. Seismology - Wikipedia

    en.wikipedia.org/wiki/Seismology

    Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i, s aɪ s-/; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies.

  7. Seismic inversion - Wikipedia

    en.wikipedia.org/wiki/Seismic_inversion

    Simultaneous Inversion (SI) is a pre-stack method that uses multiple offset or angle seismic sub-stacks and their associated wavelets as input; it generates P-impedance, S-impedance and density as outputs (although the density output resolution is rarely as high as the impedances). This helps improve discrimination between lithology, porosity ...

  8. Earthquake engineering - Wikipedia

    en.wikipedia.org/wiki/Earthquake_engineering

    Seismic performance assessment or seismic structural analysis is a powerful tool of earthquake engineering which utilizes detailed modelling of the structure together with methods of structural analysis to gain a better understanding of seismic performance of building and non-building structures. The technique as a formal concept is a ...

  9. Receiver function - Wikipedia

    en.wikipedia.org/wiki/Receiver_function

    The method is also most effective when the seismic event causing the waves occurs significantly below the Moho, which is important to avoid surface interference. [4] Over time, several seismic events can occur in the same geographic area, with each event causing a corresponding vertical waveform and horizontal waveform.
