Use your equation we just used for the last one. :)
OpenStudy (anonymous):
What exactly would the minimum detectable earthquake be though?
OpenStudy (anonymous):
\[R = \log_{?} (\frac{I}{I_o})\]
OpenStudy (anonymous):
I believe it would just be 10^4.2
OpenStudy (anonymous):
So the 4.2 earthquake is 15,848 times more intense?
