    Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen .

  4. Earthquake - Wikipedia

    en.wikipedia.org/wiki/Earthquake

    An earthquake is the shaking of the surface of Earth resulting from a sudden release of energy in the lithosphere that creates seismic waves.Earthquakes may also be referred to as quakes, tremors, or temblors.

  5. Quake (natural phenomenon) - Wikipedia

    en.wikipedia.org/wiki/Quake_(natural_phenomenon)

    The largest moonquakes are much weaker than the largest earthquakes, though their shaking can last for up to an hour, due to fewer attenuating factors to damp seismic vibrations. [1] Information about moonquakes comes from seismometers placed on the Moon from 1969 through 1972. The instruments placed by the Apollo 12, 14, 15 and 16 missions ...

  7. Doublet earthquake - Wikipedia

    en.wikipedia.org/wiki/Doublet_earthquake

    A theoretical study found about one earthquake in 15 (~7%) to be a doublet (using a narrow criterion of "doublet"), [15] but also found that in the Solomon Islands six of 57 M ≥ 6.0 earthquakes were doublets, and 4 of 15 M ≥ 7.0 earthquakes, showing that approximately 10% and 25% of those quakes were doublets.

  9. 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.
