The Richter scale measures the magnitude, M, of an earthquake as a function of its intensity, I, and the intensity of a reference earthquake, I0.

M=log(I/I0)

Which equation could be used to find the intensity of an earthquake with a Richter scale magnitude of 4.8 in reference to an earthquake with an intensity of 1?

A. I=log(1/4.8)

B. I=log(4.8)

C. 4.8=log(1/I)

D. 4.8=log(I)
