Answer to Question 1

D

Answer to Question 2

The Modified Mercalli Intensity (MMI) scale is a Roman-numeral scale from I to XII that ranges from barely felt to catastrophic total destruction. The Richter scale is a logarithmic scale which provides a number for earthquake magnitude based on the energy released during an earthquake. The moment magnitude (M) scale considers the amount of fault slippage produced by the earthquake, the size of the surface or subsurface area that ruptured, and the nature of the materials that faulted. It is more accurate for large earthquakes.
