When was the first earthquake magnitude scale developed?
Quick Answer
The first widely used magnitude scale was developed in 1935 by Charles Richter.
The Full Story
Charles Richter introduced the local magnitude scale in 1935 to compare earthquakes quantitatively. It used measurements from seismographs to estimate the size of an earthquake based on wave amplitude and distance. Although people often say “Richter scale” for any earthquake measurement, modern seismology uses several different magnitude scales. Richter’s work was a landmark in turning earthquakes into measurable scientific events.
