The Richter scale measures the intensity, I, of an earthquake (relative to a certain minimum reference Io) by a number R defined by R = log 10 (I) - log10 (10). (a) Earthquakes measuring R₁ = 7.3 and R2 = 7.7 on the Richter scale occurred in Japan in 1948 and 1983 respectively. Determine how many more times intense the 1983 earthquake was than the 1948 earthquake. Enter your answer correct to 2 decimal places. Number (b) The highest reading ever recorded on the Richter scale was 8.9. This earthquake was 1.92 times more intense than the San Francisco earthquake of 1903. Determine the Richter scale reading for the San Francisco earthquake. Enter your answer correct to 2 decimal places.
