  2. Reflection seismology - Wikipedia

    en.wikipedia.org/wiki/Reflection_seismology

    Seismic reflection exploration grew out of the seismic refraction exploration method, which was used to find oil associated with salt domes. [2] Ludger Mintrop, a German mine surveyor, devised a mechanical seismograph in 1914 that he successfully used to detect salt domes in Germany. He applied for a German patent in 1919 that was issued in 1926.

  3. 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.

    The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear tests.

  5. Earthquake environmental effects - Wikipedia

    en.wikipedia.org/wiki/Earthquake_environmental...

    Both surface deformation and faulting and shaking-related geological effects (e.g., soil liquefaction, landslides) not only leave permanent imprints in the environment, but also dramatically affect human structures. Moreover, underwater fault ruptures and seismically triggered landslides can generate tsunami waves.

  6. Seismic velocity structure - Wikipedia

    en.wikipedia.org/wiki/Seismic_Velocity_Structure

    This is an illustration of Snell's Law. A seismic wave coming with the path of the red line would refract when it passes through the surface of medium change. Seismic waves travelling at a critical angle (blue line) will be refracted critically with an angle of refraction equal to 90°. An illustration of seismic reflection and refraction ...

  8. Exploration geophysics - Wikipedia

    en.wikipedia.org/wiki/Exploration_geophysics

    Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods at the surface of the Earth, such as seismic, gravitational, magnetic, electrical and electromagnetic, to measure the physical properties of the subsurface, along with the anomalies in those properties.

  9. Induced seismicity - Wikipedia

    en.wikipedia.org/wiki/Induced_seismicity

    With appropriate management, the number and magnitude of induced seismic events can be decreased, significantly reducing the probability of a damaging seismic event. [59] Induced seismicity in Basel led to suspension of its HDR project. A seismic hazard evaluation was then conducted, which resulted in the cancellation of the project in December ...
