Question

Please help! An earthquake has a Richter number of 4.2. How many times more intense than the minimum detectable earthquake is the earthquake? Round your answer to the nearest whole number.

Answer 1

Use your equation we just used for the last one. :)

Answer 2

What exactly would the minimum detectable earthquake be though?

Answer 3

\[R = \log_{?} (\frac{I}{I_o})\]

Answer 4

I believe it would just be 10^4.2

Answer 5

So the 4.2 earthquake is 15,848 times more intense?

Answer 6

Is this correct?
