The scale used today to measure earthquakes is the moment magnitude scale (Mw). It is the most widely used scale for measuring the size of earthquakes because it provides a more accurate representation of an earthquake's size and energy release compared to older scales like the Richter scale.
Scales are measuring equipment to determine the mass of something

The device used for measuring earthquakes is called a seismometer.
