Which of the following is CORRECT regarding the moment magnitude scale?
A)It is a closed scale that begins at 0.0 and ends at 10.0.
B)It is the same as the Mercalli scale.
C)It is a scale of magnitude based on arithmetical progressions (1,2,3,4,etc.).
D)It considers the amount of fault slippage produced by the earthquake,the size of the surface (and subsurface)area that ruptured,and the nature of the materials that faulted.

The moment magnitude scale considers the amount of fault slippage produced by the earthquake, the size of the surface (and subsurface) area that ruptured, and the nature of the materials that faulted. It is not a closed scale and does not use arithmetical progressions. It is also different from the Mercalli scale, which measures the intensity of shaking and damage caused by an earthquake.
