In a place an earthquake occurred with an intensity of 9.1.The Ritcher Scale(the instrument used for measuring the intensity of an earthquake)can only measure the intensity upto 9.Then how did they know or measure that the earthquake that occurred had the intensity 9.1?
The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the energy released by an earthquake. The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude. So as its a base-10 scale we can measure the intensity above 9.
