  3. Seismic intensity scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_intensity_scales

    Seismic intensity scales categorize 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.

  4. Seismic magnitude scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_magnitude_scales

    As the energy of a wave is proportional to A 1.5, where A denotes the amplitude, each unit of magnitude represents a 10 1.5 ≈ 32-fold increase in the seismic energy (strength) of an earthquake. [13] Second, Richter arbitrarily defined the zero point of the scale to be where an earthquake at a distance of 100 km makes a maximum horizontal ...
