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:
[tex]RichterScale(1)=Log(10^{1})=1[/tex]
An earquake of 2.0 at Richter scale is equal to:
[tex]RichterScale(2)=Log(10^{2})=Log(100)=2[/tex]
and so...
Therefore,
An earthquake of 4.0 at the Richter scale is equal to:
[tex]RichterScale(4)=Log(10^{4})=Log(10000)=4[/tex]
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!
