Charles Francis Richter (April 26, 1900 - September 30, 1985) was an American seismologist and physicist. Richter is most famous as the creator of the Richter magnitude scale which, until the development of the moment magnitude scale in 1979, quantified the size of earthquakes. Inspired by Kiyoo Wadati's 1928 paper on shallow and deep earthquakes, Richter first used the scale in 1935 after developing it in collaboration with Beno Gutenberg; both worked at California Institute of Technology. The quote "logarithmic plots are a device of the devil" is attributed to Richter.

Seismology is the study of seismic waves, energy waves caused by rock suddenly breaking apart within the earth or the slipping of tectonic plates. We know these as events as earthquakes. They can also be caused by explosions from volcanic eruptions and testing of nuclear bombs.

Seismology means study of earth moments like Earth quakes. People who make research on seismic are known as seismologists.
