Question

Quizplus · Accepted Answer

The moment magnitude scale, also known as the Richter magnitude scale, is the most commonly used scale by seismologists to measure the magnitude of earthquakes. The scale measures the amount of energy released by an earthquake and is based on the logarithm of the maximum amplitude of ground motion recorded on a seismogram.
