How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter.Small earthquakes have about the same value on the Richter scale and the moment magnitude scale, so Richter is fine for those. But, larger earthquakes are better measured as moment magnitude, where Richter becomes less accurate. All the earthquake magnitudes you will see here use the newer moment magnitude scale.On the Richter or magnitude moment scale, what is the difference in energy released by an earthquake that is a 7.2 versus an 8.2 in magnitude?
