The magnitude of an earthquake is given by the Richter scale, whose formula is R = log where I is the intensity of the earthquake and Io is the intensity of a 16
minimal earthquake and used for comparison purposes. The 1906 city A earthquake had a magnitude of 8.07, and the 1964 city B earthquake had a magnitude of
6.8. Compare the intensities of the two earthquakes.
The 1906 city A earthquake was approximately times more intense than the 1964 city B earthquake.
