In 1989, the Loma Prieta earthquake damaged the city of San Francisco with an intensity of approximately 10 6.9 I 0 . Film footage of the 1989 earthquake was captured on a number of video cameras including a broadcast of Game 3 of the World Series played at Candlestick Park. (See Example 10) a. Determine the magnitude of the Loma Prieta earthquake. b. Smaller earthquakes occur daily in the San Francisco area and most are not detectable without a seismograph. Determine the magnitude of an earthquake with an intensity of 10 3.2 I 0 . c. How many times more intense was the Loma Prieta earthquake than an earthquake with a magnitude of 3.2? Round to the nearest whole unit.
