How is the strength of an earthquake measured.
The Richter magnitude scale is used to measure the strength or magnitude of an earthquake. It is the most commonly used scale and assigns a number between 1 and 10 based on the amount of energy released by the earthquake. The larger the magnitude, the greater the intensity of the earthquake. About.

Figure 3-17 relates earthquake intensity to the maximum amount of ground acceleration (peak ground acceleration, or PGA) that is measured with a special instrument called a strong-motion accelerograph.Measurement of the severity of an earthquake can be expressed in several ways, but the two most common scales used by seismologists are intensity and magnitude. Earthquake intensity. Intensity is a qualitative measure of the strength of shaking caused by an earthquake determined from the observed effects on people, objects and buildings. Richter Scale is the earthquake measurement scale that is used to measure the strength of the Earthquake or the amount of energy released during the earthquake. It was invented by American seismologist Charles F. Richter of the California Institute of Technology as a mathematical device that was used to compare the size of earthquakes in 1935.Earthquakes can be measured in two ways.
