What the scale most widely used by scientists today for measuring earthquakes is the?

The most widely used scale by scientists today for measuring earthquakes is the Moment Magnitude Scale (Mw). This scale quantifies the total energy released by an earthquake, providing a more accurate measure than previous scales, especially for larger events. It is based on the seismic moment, which considers the area of the fault that slipped, the average amount of slip, and the rigidity of the rocks involved. This scale has largely replaced the Richter scale for scientific assessments.
