[3 marks] The magnitude R (measured on the Richter scale) of an earthquake is defined as R = log10 I, where I is the earthquake's intensity. a. One of the largest recorded earthquakes occurred in Chile, 1977. Determine the intensity of the earthquake if its reading on the Richter scale was R = 9.5. b. Over the last century, Southern California has experienced five "major" earthquakes that had a magnitude over R = 7. The readings averaged a magnitude of R = 7.2 To one decimal place, how many times more intense was the earthquake in Chile than the average "major" earthquake in Southern California in the last century
