The Moment magnitude scale (which replaced the Richter scale) and the Modified Mercalli scale are used to determine the strength of an earthquake.
The Moment magnitude scale is used by seismologists to rate the energy released by earthquakes.
The Modified Mercalli scale is used to measure the intensity of an earthquake, and the amount of damage it causes. This value is derived from reports by witnesses of the earthquake, the damage caused to buildings and other infrastructure and the measured ground accelerations from seismometers.
Please see the related questions for more information.
One is the Richter scale, which measures waves and gives us a measure of the magnitude of the earthquake. The other is the Mercalli scale, which is based on the amount of damage done.
Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.
The amplitude of seismic waves from an earthquake is is measured by a seismometer. From this an estimate can be made of the amount of energy released by an earthquake (this is known as magnitude). The magnitude of an earthquake is controlled by the amount of energy stored within the deformed rocks of the crust. This is in turn a function of the elastic moduli of the crust, the cross sectional area of the fault rupture zone and the amplitude of the displacement on the fault.
A seismogram is a graph that displays the ground motion recorded by a seismometer during an earthquake. Seismograms are used to determine important characteristics of the earthquake, such as its magnitude, depth, and location.
Earthquakes can be measured on different scales because there are different ways to quantify their size and impact. The two commonly used scales are the Richter scale and the moment magnitude scale, which are based on different aspects of the earthquake, such as the amplitude of seismic waves or the total energy released. This is why you may see the same earthquake measured with different magnitudes on different scales.
The strength of an earthquake is typically measured using the moment magnitude scale (Mw), which takes into account the seismic energy released by the earthquake. This scale provides a single number that represents the overall size of the earthquake. Another commonly used scale is the Richter scale, which measures the amplitude of seismic waves.

Richter scales are used to measure the magnitude of an earthquake. There is no specific unit used for earthquakes. I hope this helps. =)

Earthquake strength is measured using a magnitude scale. For small to moderate strength Earthquakes (< magnitude 7) the Richter scale is used. For Earthquakes between 7 and 8 the body and surface magnitude scales are used and for earthquakes larger than 8, the moment magnitude scale is used.

Lilly, who is a scientist, used a seismograph to determine the strength of the earthquake that had just hit Haiti.
