Question

Magnitude of an earthquake : M = log I S What is the magnitude of an earthquake that is 10,000 times more intense than a standard earthquake? M =

Answer 1

First one is 4

Second one is 3.7

Explanation:

Answer 2

Hello!

The answer is: 4.0 (at Richter scale)

Why?

The answer is 4.0 Assuming the standard earthquake as 1.0 (at Richter scale).

An earthquake of 1.0 at Richter scale is equal to:

`RichterScale(1)=Log(10^(1))=1`

An earquake of 2.0 at Richter scale is equal to:

`RichterScale(2)=Log(10^(2))=Log(100)=2`

and so...

Therefore,

An earthquake of 4.0 at the Richter scale is equal to:

`RichterScale(4)=Log(10^(4))=Log(10000)=4`

So, it means that an earthquake with 4.0 magnitude at the Richter scale is 10000 times more intense than a standard earthquake, assuming it as 1.0 at Richter scale magnitude.

Have a nice day!
