Concept explainers
Richter Scale The Richter scale is used to measure the intensity of earthquakes. The Richter scale rating of an earthquake is given by the formula
a. The San Francisco earthquake of 1906 is estimated to have registered
b. The Japan earthquake of 2011 registered 9.0 on the Richter scale. Compare the two: The energy released in the 1906 earthquake was what percentage of the energy released in the 2011 quake?
c. Solve the equation given above for E in terms of R.
d. Use the result of part (c) to show that if two earthquakes registering
e. Fill in the blank: If one earthquake registers 2 points more on the Richter scale than another, then it releases __________times the amount of energy.

- In 1906, San Francisco experienced an intense earthquake with a magnitude of 7.8 on the Richter scale. In 1989, the Loma Prieta earthquake also affected the San Francisco area, and measured 6.9 on the Richter scale. Compare the intensities of the two earthquakes.arrow_forwardIn 2014, Chile experienced an intense earthquake with a magnitude of 8.2 on the Richter scale. In 2014, Los Angeles also experienced an earthquake which measured 5.1 on the Richter scale. Compare the intensities of the two earthquakes.arrow_forwardWhat type (s) of translation(s), if any, affect the range of a logarithmic function?arrow_forward
