One example of a seismograph is the Richter scale. Developed by Charles F. Richter in 1935, it measures the magnitude of earthquakes based on the amplitude of seismic waves recorded by seismographs. The Richter scale assigns a numerical value to the size of an earthquake, with each whole number increase representing a tenfold increase in the amplitude of the seismic waves and approximately 31.6 times more energy released. For example, an earthquake with a magnitude of 5.0 is considered moderate, while a magnitude of 8.0 or higher is classified as great.
