The magnitude of an earthquake is measured on the Richter

Last updated: 7/29/2022

The magnitude of an earthquake is measured on the Richter scale as a logarithm of the intensity of the shock wave. For magnitude R and intensity I, the formula is R = log(1). The September 20, 1999 earthquake in Taiwan measured 7.7 on the Richter scale. The Beverly Hills earthquake in January 23, 2002 measured 1.8 on the scale. How many times more intense was the Talwan earthquake than the Beverly Hills earthquake? Round your answer to two decimal places, if necessary.
