AND
LOGARITHMIC FUNCTIONS



EARTHQUAKE PROBLEMS:



Work the following problems. Click on solution if you want to review the solution.



Problem 1: Early in the century an earthquake measured 8.0 on the Richter scale. In the same year, another earthquake was recorded that measured six time stronger on the Richter scale. What was the magnitude of the earthquake of the stronger earthquake?



Solution




Problem 2: A recent earthquake measured 6.8 on the Richter scale. How many times more intense was this earthquake than an earthquake that measured 4.3 on the Richter scale?



Solution




Problem 3: If one earthquake is 31 times as intense as another, how much larger is its magnitude on the Richter scale?
