Question

what is the magnitude of an earthquake that is 10000 times more intense than a standard earthquake?

Answer 1

Substitute \(10000 I_{0}\) in for \(I \) to get \[R(10000 I _{0})=\log\left(\frac{10000 I _{0} {I_{0}}\right =\log(10000)=4 mbox{.}\].So an earthquake of intensity 10,000 times I_{0} would have a magnitude of 4.0 on Richter scale.

Answer 2

What is the magnitude of an earthquake that is 10,000 times more intense than a standard earthquake?
