The term that describes the measurement of energy released during an earthquake is "magnitude." Specifically, magnitude quantifies the amount of energy released at the source of the earthquake and is usually represented on a logarithmic scale. The most common scale for measuring magnitude is the moment magnitude scale, which provides a more accurate measurement of the energy released than earlier scales like the Richter scale, especially for larger earthquakes.

Magnitude is distinct from intensity, which measures the effects and damage caused by the earthquake at various locations. While intensity is related to the observed impact of the earthquake on the Earth's surface and structures, magnitude is a more fundamental measure that reflects the energy released during the seismic event.

Energy is a general term and does not specify how it's measured in relation to earthquakes. The Richter scale specifically refers to the older method of quantifying the magnitude of an earthquake, but it is largely considered less accurate than newer scales.

Thus, the correct understanding of magnitude as the measurement of energy released during an earthquake is crucial in both seismology and related disaster management efforts.
