The Richter scale is logarithmic, meaning each whole number increase on the scale represents a tenfold increase in measured amplitude. Thus, an earthquake that measures 2 on the Richter scale is 10^2 or 100 times more intense than the smallest measurable activity, which is defined as a magnitude of 0.
