The natural phenomenon measured using the Richter scale is an earthquake. The Richter scale quantifies the magnitude of seismic waves generated by an earthquake, allowing scientists to gauge the energy released during the event. Developed in 1935 by Charles F. Richter, this logarithmic scale assigns a numerical value to earthquakes, with higher numbers indicating stronger quakes. While the Richter scale is still widely recognized, it has largely been replaced by the moment magnitude scale (Mw) in recent research, which provides a more accurate measure for larger earthquakes.
