Compare and contrast the different ways of measuring the intensity and/or magnitude of earthquakes? Which do you think is best, and why?
What will be an ideal response?
Scientists rate earthquakes on either a qualitative damage intensity scale or a quantitative magnitude scale. The Modified Mercalli Intensity (MMI) scale is a qualitative, 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.
