62. Mag nitude of Earthquakes 0n the Richter scale, the magnitude R of an earthquake is given by the formula 2210in 0 where I is the intensity of the earthquake being measured and In is the standard reference intensity. a. Express the intensity I of an earthquake of magnitude R = 5 in terms of the standard intensity In. b. Express the intensity I of an earthquake of magnitude R = 8 in terms of the standard intensity In. How man},r times greater is the intensity of an earthquake of magnitude 8 than one of magnitude 5? c. In modern times, the greatest loss of life attributable to an earthquake occurred in Haiti in 2010. Known as the Haiti earthquake, it registered 7.0 on the Richter scale. How does the intensity of this earthquake compare with the intensity of an earthquake of magnitude R = 5
