Which of the following scales measures earthquake magnitude?

Answer: The correct answer is Option C. Moment magnitude scale. Earthquake magnitude is a measure of the energy released during an earthquake. The moment magnitude scale is the most commonly used scale to measure earthquake magnitude. It measures the energy released by an earthquake based on the amount of displacement that occurs along the fault and the area of the fault that ruptures. The Richter scale measures the amplitude of the largest seismic wave recorded by a seismograph, whereas the Mercalli scale measures the intensity of shaking at a specific location. There is no such thing as a seismograph scale. Explanation: Earthquake magnitude is a measure of the energy released during an earthquake.
