Seismometers measure the amplitude of seismic waves as well as the velocity and acceleration of the grounds surface. This allows seismologists to estimate the magnitude of an earthquake (the amount of energy released). From the energy emission per unit time they can estimate the power of the earthquake.
They both based on the amount of energy that is released during earthquake
The "moment" magnitude of an earthquake is a measure of how much energy is released when an earthquake occurs. It is derived from the stiffness or rigidity of the rock mass around the fault rupture zone, the length of the fault that moved and the cross sectional area of the fault zone. Seismologists can also estimate its value based on the amplitude of seismic waves recorded on a seismometer. The Richter scale (currently used to measure small and medium strength earthquakes with magnitudes below 7.0 - larger earthquakes magnitudes are measured using the moment magnitude scale as described above) is also a measure of the amount of energy released by an earthquake and is derived based on the maximum amplitude of the seismic waves as recorded on seismometers.
The force or category of an earthquake is typically measured using the Richter scale or the Moment Magnitude scale (Mw). The Richter scale quantifies the seismic energy released at the earthquake's source, while the Moment Magnitude scale provides a more accurate measure of the earthquake's size, especially for larger events, by considering the fault area and the amount of slip. Seismographs detect and record the vibrations generated by the earthquake, which are then analyzed to determine the magnitude. Additionally, the Modified Mercalli Intensity scale assesses the earthquake's effects on people, structures, and the Earth's surface.
The Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it released

This is known as the magnitude of the earthquake.
Earthquake magnitude is a measure of the energy released during an earthquake. It is typically measured using the Richter scale or the moment magnitude scale. These scales assign a numerical value to quantify the seismic energy released, with each whole number increase representing a tenfold increase in amplitude.
The Richter scale measures the magnitude of an earthquake, which represents the amount of energy released at the earthquake's source. It is a logarithmic scale, where each whole number increase corresponds to a tenfold increase in amplitude of the seismic waves.
The amount of energy released by an earthquake is measured on the moment magnitude scale, often referred to as just magnitude. This scale takes into account the seismic moment, which is a measure of the total energy released during an earthquake. The magnitude is expressed in whole numbers and decimal fractions.
An earthquake's magnitude is a measure of how strong it is
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.

to measure the amount of energy released during an earthquake
Magnitude scales are used to assess the amoiunt of energy relaed by an earthquake. For small and medium strength earthquakes (less than magnitude 7.0) the Richter scale is used. For larger earthquakes than this, the moment magnitude scale is used.
The energy released by an earthquake is measured using a seismometer. The amplitude of the seismic waves recorded by a seismometer are in-turn plugged into an equation that gives a value on the magnitude scale.
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
