Saffir-Simpson Scale Modified Mercalli Scale Richter Magnitude Scale Moment Magnitude Scale
I gave my students this multiple choice question: Which scale is used to report the intensity of an earthquake?

Only one answer is correct among these 4 choices:
- Saffir-Simpson Scale
- Modified Mercalli Scale
- Richter Magnitude Scale
- Moment Magnitude Scale

Could you tell me which one is correct?

Modified Mercalli Scale
