What is the earthquakes magnitude is a measure of the?

Earthquake magnitude is a measure of the energy released during an earthquake, quantified on a logarithmic scale. It reflects the amplitude of seismic waves recorded by seismographs, allowing for a standardized comparison of earthquakes' sizes. The most commonly used scale is the Richter scale, although the moment magnitude scale (Mw) is now preferred for measuring larger events. Higher magnitudes indicate more powerful earthquakes, which can lead to greater damage and impact.
