Origin[edit | edit source]

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.

Beno Gutenberg (June 4, 1889 – January 25, 1960) was a German-American seismologist who made several important contributions to the science. He was a colleague and mentor of Charles Francis Richter at the California Institute of Technology and Richter's collaborator in developing the Richter magnitude scale for measuring an earthquake's magnitude.

The scale developed by Richter and Gutenberg (which became known by Richter's name only) was an absolute measure of an earthquake's intensity. Richter used a seismograph – an instrument generally consisting of a constantly unwinding roll of paper, anchored to a fixed place, and a pendulum or magnet suspended with a marking device above the roll – to record actual earth motion during an earthquake. The scale takes into account the instrument's distance from the epicenter, or the point on the ground that is directly above the earthquake's origin. Richter chose to use the term "magnitude" to describe an earthquake's strength because of his early interest in astronomy; stargazers use the word to describe the brightness of stars. Gutenberg suggested that the scale be logarithmic, so that a quake of magnitude 7 would be ten times stronger than a 6, a hundred times stronger than a 5, and a thousand times stronger than a 4.

Effects[edit | edit source]

Detects any level of ground vibration in the immediate area. Shows detection as lines drawn on the paper roll by the pen. Once a major vibration (scale 5+) stops, the roll resets as blank. If physically moved by a force other than the detected vibration, it generates its own earthquakes, amplified on a scale of 1-10 (i.e. bump = scale 1. Knock over = scale 10). It is stored in a suspension sphere for safety, dampening all dynamic loads throughout the body.
