As a basis of comparison to a known standard. This helps in better understanding the nature of earthquakes over a long period of time.
With a measuring tape
The device used for measuring earthquakes is called a seismometer.
They're not.
there is 1 currently used but past years they have used two diffrent scales the Mercalli scale (Early in the twentieth century) the The Richter (1930s-1980s) and now currently The Moment Magnitude Scale some news channel refer the moment magnitude scale as the Richter scale but they are two diffrent things hopes this helps

The magnitude, Richter scale, and seismograph.
There are actually about 20 different ways of measuring earthquakes. The 3 main are the Mercalli scale, richter scale, and moment magnitude scale
Moment Magnitude, Ritcher Scale and Mercili Scale.
Scales work by measuring things. Thermometer scales work by measuring the temperature of the air and certain liquids for example.
Mercalli and Richter scales
They are scales for measuring temperature.
different scals
Whenever the data covers a very large range of values a log scale if very useful. Earthquakes and hearing are common examples.
