The strength (or more correctly the frequency and amplitude) of an earthquake is measured using a device known as a seismometer.
Estimates of the energy released by an earthquake (described as it's magnitude) are made using the Moment Magnitude scale. Estimates of this may also be derived from the amplitude of the seismic waves recorded on the seismometer using the now obsolete Richter or Local Magnitude scale as well as the Moment Magnitude scale.
