<u>Step-by-step explanation:</u>
Here we have , to find the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake . Let's find out:
We know that , Value of earthquake is given by formula
⇒ , Where M is magnitude of earthquake
is the measured magnitude of intensity of earthquake .
is the standard magnitude of intensity of earthquake .
According to question , , Hence
⇒
⇒
⇒
⇒ { On rounding off we get }
⇒
