Question

The Richter scale is used for measuring the magnitude of an earthquake. The Richter magnitude is given R = 0.67log(0.37E) + 1.46 where E is the energy (in kilowatt hours) released by the earthquake. If an earthquake release 1,770,000 kilowatt hours of energy, what is the earthquake’s magnitude?

    Answer:

    R=3.897

    Step-by-step explanation:

    Given the magnitude measured by the Ritcher scale is given as;

    R = 0.67log(0.37E) + 1.46  where E= is the energy (in kilowatt hours)

    If E=1,770,000 then

    R= 0.67log(0.37*1770000)

    R=0.67log(654900)

    R=0.67*5.81617

    R=3.897
