    An earthquake is what happens when the seismic energy from plates slipping past each other rattles the planet's surface. Those seismic waves are like ripples on a pond, the USGS said.

    For instance, an earthquake of magnitude 6.0 releases approximately 32 times more energy than a 5.0 magnitude earthquake and a 7.0 magnitude earthquake releases 1,000 times more energy than a 5.0 magnitude earthquake. An 8.6-magnitude earthquake releases the same amount of energy as 10,000 atomic bombs of the size used in World War II. [18]

  4. Quake (natural phenomenon) - Wikipedia

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

    An earthquake is a phenomenon that results from the sudden release of stored energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes cause tsunamis, which may lead to loss of life and destruction of property. An earthquake is ...

    A major earthquake measuring 7.4 hit Taiwan early Wednesday, killing 9 and injuring at least 1,000. A 7.4 earthquake is exponentially more destructive than the 4.8 quake that struck central New ...

  6. Seismic wave - Wikipedia

    en.wikipedia.org/wiki/Seismic_wave

    Following an earthquake event, S waves arrive at seismograph stations after the faster-moving P waves and displace the ground perpendicular to the direction of propagation. Depending on the propagational direction, the wave can take on different surface characteristics; for example, in the case of horizontally polarized S waves, the ground ...

    Reports of multicolor “earthquake lights,” such as the ones seen in videos captured before Morocco’s 6.8 magnitude quake on September 8, go back centuries to ancient Greece.

  8. Earthquake cycle - Wikipedia

    en.wikipedia.org/wiki/Earthquake_Cycle

    A complete earthquake cycle can be divided into interseismic, preseismic, coseismic and postseismic periods. [1] During the interseismic period, stress accumulates on a locked fault due to plate motion. [2] In the preseismic period, this stress is approaching the rupture limit, and some earthquake precursors may occur. [1]

  9. 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.
