MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Magnitude of Earthquakes On the Richter scale, the magnitude R of an earthquake is given by the formula R = log where I is the intensity of the earthquake being measured and I, is the standard reference intensity. (a) Express the intensity I of an earthquake of magnitude R = 5 in terms of the standard intensity I,. (b) Express the intensity I of an earthquake of magnitude R = 8 in terms of the standard intensity ,. How many times greater is the intensity of an earthquake of magnitude 8 than one of magnitude 5? times greater (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? Need Help? Read It
