The intensitylevels I of two earthquakes measured ona seismograph can be compared by the formula log I 1 I 2 = M 1 − M 2 where M is the magnitude given by the Richter Scale. In August 2009 , an earthquake of magnitude 6.1 hitHonshu, Japan. In March 2011 , that same regionexperienced yet another, more devastating earthquake, this time with a magnitude of 9.0. [ 23 ] Haw many timesgreater was the intensity of the 2011 earthquake?Round to the nearest whole number.
