The scale was devised by American geologist Charles W. Richter (1900-1985) in 1935.

The highest number on the Richter scale is 10. However, in practice, most earthquakes do not exceed a magnitude of 9.5.
Ricther Scale: A scale of 1 to 10. I think the highest ever recorded was somewere in China in 8.9

An earthquake of magnitude 8.4 on the Richter scale is 1000 times more powerful than an earthquake of magnitude 6.4 on the Richter scale. The Richter scale is logarithmic, meaning that each whole number increase represents a tenfold increase in amplitude and approximately 31.6 times more energy release.
chromatic scale
Modern thermometers are made of alcohol or Mercury, and uses the Fahrenheit scale and the Celsius scale.

The chromatic scale is made up entirely of half steps.
