The intensity of an earthquake is measured relative to the intensity of a standard zero-level earthquake of intensity I 0 . The relationship is equivalent to I = I 0 10 R , where R is the Richter scale

The intensity of an earthquake is measured relative to the intensity of a standard zero-level earthquake of intensity I0. The relationship is equivalent to I = I0 × 10R, where R is the Richter scale measure. For example, if an earthquake has magnitude 5.0 on the Richter scale, then its intensity is calculated as

which is 100,000 times as intense as a zero-level earthquake.To compare an earthquake that measures 8.1 on the Richter scale to one that measures 5.2, find the ratio of the intensities.image


Therefore, an earthquake that measures 8.1 on the Richter scale is almost 800 times as intense as one that measures 5.2.image
