Moment Magnitude, Ritcher Scale and Mercili Scale.
The two scales that are used today are the Moment magnitude scale (which replaced the Richter scale) and the Mercalli scale.
There are actually about 20 different ways of measuring earthquakes. The 3 main are the Mercalli scale, richter scale, and moment magnitude scale
Mercalli and Richter scales
The Richter scale, which measures the magnitude of earthquakes, was developed by Charles Richter in 1935.
Richter is a scale widely used for measuring intensity of earthquakes.
Laser-ranging devices us laser beams to detect the fault movements that cause earthquakes.
The magnitude, Richter scale, and seismograph.
As a basis of comparison to a known standard. This helps in better understanding the nature of earthquakes over a long period of time.

Scales work by measuring things. Thermometer scales work by measuring the temperature of the air and certain liquids for example.
