There is 20 times more ground shaking associated with a magnitude 7 earthquake on the Richter scale compared to a magnitude 5 earthquake.

Question

Quizplus · Accepted Answer

The Richter scale is logarithmic, meaning each whole number increase on the scale represents a tenfold increase in measured amplitude. Therefore, a magnitude 7 earthquake would have 100 times more ground shaking than a magnitude 5 earthquake (10^2, since the difference is 2 magnitudes on the scale).
