Abstract
The Richter Scale is a quantitative measure of the magnitude of an earthquake. It has been invented in 1935 by Charles F. Richter and is based the amplitude measured by a seismograph with a correction factor for the distance from the centre of the earthquake from which the measurement is taken. This measurement is totally independent from the damage that it might cause. Although invented in 74 years ago, it is still in use and has many advantages compared to the other scales used for earthquakes.

Chapter Summaries
The Richter Scale: This chapter introduces the Richter Scale as a method for comparing earthquakes. It explains that the scale, invented in 1935, measures ground motion and is calculated from the measured peak amplitude of an earthquake recorded by seismographs. The chapter details how seismographs work, from simple early models to more sophisticated modern instruments using levers and electronics to achieve greater accuracy. It also introduces the formula used to calculate magnitude, incorporating a distance correction factor to account for variations in readings based on the seismograph's distance from the earthquake's epicenter. The chapter concludes by mentioning the use of a nomogram for quick estimation of magnitude and notes that a tenfold increase in amplitude corresponds to an increase of one unit on the Richter Scale.
History: This section provides biographical information about Charles F. Richter, the creator of the Richter Scale. It highlights his education and career path, emphasizing his role as an American physicist and his contributions to the field of seismology. While details about his life and other achievements are mentioned, the main focus is on his invention of the scale that bears his name and its lasting impact on the measurement of earthquakes.
