B)Mercalli scale
C)seismic-moment magnitude scale

Question

Quizplus · Accepted Answer

The seismic-moment magnitude scale takes into account the type of rock that has been fractured, as it is determined by the seismic moment of an earthquake, which is related to the area of the fault that ruptured and the average slip of the fault. This takes into account the strength and rigidity of the rock, which affects the amount of energy released during an earthquake. The Richter scale, on the other hand, is a logarithmic measurement of the amplitude of waves recorded on a seismogram, and the Mercalli scale is a qualitative assessment of the intensity of shaking and damage observed at a particular location.
