Richter scale values above 7 are not accurate. The ______ scale is a more objective method of measuring the energy of a large earthquake.

Question

Quizplus · Accepted Answer

The moment magnitude scale is a more accurate measure of earthquake energy as it takes into account the actual amount of energy released during an earthquake, whereas the Richter scale only measures the amplitude of the largest wave on a seismogram. Additionally, the Richter scale is only accurate up to values of around 7, whereas the moment magnitude scale can accurately measure earthquakes of larger magnitudes.
