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. The word tremor is also used for non-earthquake seismic rumbling . In its most general sense, an earthquake is any seismic event ...

Seismology ( / saɪzˈmɒlədʒi, saɪs -/; 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 the Earth or other planetary bodies. It also includes studies of ...

v. t. e. The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it ...
Seismic tomography. Seismic tomography or seismotomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. P-, S-, and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the seismograph array coverage. [1]
