  2. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.

  3. Elastic-rebound theory - Wikipedia

    en.wikipedia.org/wiki/Elastic-rebound_theory

    In geology, the elastic-rebound theory is an explanation for how energy is released during an earthquake. As the Earth's crust deforms, the rocks which span the opposing sides of a fault are subjected to shear stress. Slowly they deform, until their internal rigidity is exceeded.

    While earthquakes are most common along the fault lines of tectonic plates—of which there are seven major ones in the world—the seismic quakes can actually hit anywhere, at any time, according ...

  6. Tectonic uplift - Wikipedia

    en.wikipedia.org/wiki/Tectonic_uplift

    Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...

  7. Seismic tomography - Wikipedia

    en.wikipedia.org/wiki/Seismic_tomography

    This allows for the detection of seismic waves refracted from sub-crustal depths and can determine continental architecture and details of plate margins. These two methods are often used together. Local earthquake tomography is used in seismically active regions with sufficient seismometer coverage. Given the proximity between source and ...

  8. Convergent boundary - Wikipedia

    en.wikipedia.org/wiki/Convergent_boundary

    The 2004 Indian Ocean earthquake and tsunami was triggered by a megathrust earthquake along the convergent boundary of the Indian plate and Burma microplate and killed over 200,000 people. The 2011 tsunami off the coast of Japan , which caused 16,000 deaths and did US$360 billion in damage, was caused by a magnitude 9 megathrust earthquake ...

  9. Vertical displacement - Wikipedia

    en.wikipedia.org/wiki/Vertical_displacement

    Subsidence at a divergent plate boundary is a form of vertical displacement which occurs when a plate begins to split apart. [2] As intrusive magma widens the rift zone of a divergent plate boundary the layers of crust on the surface above the rift will subside into the rift, creating a vertical displacement of those layers of surface crust.
