If M represents the magnitude of an earthquake in the Ritcher scale and I the intensity of the earthquake, then: M = log(I/S)

S being the average intensity of a standard earthquake for comparison

Question:

- Earthquake 1 has a magnitude of 8.7 and Intensity I
- Earthquake 2 has a magnitude of 8 and Intensity I'
- I = k*I'
