Answer:

Magnitude of an earthquake = 4

Explanation:

If the given equation represents the magnitude of an earthquake

M = log (
(I)/(S))

Here
((I)/(S)) is the ratio of Intensity and standard earthquake.

We have to calculate the magnitude of an earthquake that is 10000 times more intense than a standard earthquake.

Means ratio I:S is 10000.

(I)/(S)=(10000)/(1)

Then Magnitude =
log ((10000)/(1))

Magnitude = log (10000) =
log (10^(4))

= 4 log(10) = 4×1 = 4
