What are the different ways of measuring the intensity and/or effects of earthquakes? Which do you think is best, and why?
What will be an ideal response?
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.
