Answer: measures the size of an earthquake in terms of the damage it does (its intensity).
Explanation: The Richter scale also known as the Richter magnitude scale or Richter's magnitude scale is a logarithmic scale used to express the energy released by an earthquake, each increase of 1 representing a 32-fold increase in energy.
This scale was developed by Charles F. Richter and presented in his landmark 1935 paper. This scale measures the size of an earthquake in terms of its intensity.
