GEOLOGY

Detailed explanation-1: -The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

Detailed explanation-2: -The Richter scale was originally devised to measure the magnitude of earthquakes of moderate size (that is, magnitude 3 to magnitude 7) by assigning a number that would allow the size of one earthquake to be compared with another.

Detailed explanation-3: -Richter scale measures magnitude of earthquake whereas Mercalli scale is used to measure the intensity of earthquake.

Detailed explanation-4: -1. Richter Scale is used to measure the scale of absolute ‘Magnitude’ of an earthquake based on the amount of seismic energy released. 2. Mercalli scale measures the ‘Intensity’ of an earthquake based on based on the amount of destruction caused.

Detailed explanation-5: -The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake.
