The Richter scale [1] (/ ˈ r ɪ k t ər /), 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 Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". [3]
Magnitude is an estimate of the relative "size" or strength of an earthquake, and thus its potential for causing ground-shaking. It is "approximately related to the released seismic energy." [1] Intensity refers to the strength or force of shaking at a given location, and can be related to the peak ground velocity.
A particular problem was that the M s scale (which in the 1970s was the preferred magnitude scale) saturates around M s 8.0 and therefore underestimates the energy release of "great" earthquakes [13] such as the 1960 Chilean and 1964 Alaskan earthquakes.
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 ...
In seismology, the Gutenberg–Richter law[ 1] ( GR law) expresses the relationship between the magnitude and total number of earthquakes in any given region and time period of at least that magnitude. or. where. is the number of events having a magnitude , and are constants, i.e. they are the same for all values of and .

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. Then they separate with a rupture along the fault; the sudden ...
v. t. e. Seismic intensity scalescategorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking.
