What is the magnitude of an earthquake that is 5,011 times more intense than a standard earthquake? Round the answer to the nearest tenth.

Respuesta :

Answer:

The magnitude of the earthquake is 3.7 (approx)

Step-by-step explanation:

We know that the magnitude of an earthquake is,

[tex]M=log(\frac{I_1}{I_0})[/tex]

Where, [tex]I_0[/tex] is the standard intensity of earthquake,

[tex]I_1[/tex] is the measured intensity of earthquake,

Here, [tex]I_1=5011I_0[/tex]

[tex]\implies M=log(\frac{5011I_0}{I_0})[/tex]

[tex]M=log(5011)=3.699924\approx 3.7[/tex]

Hence, the magnitude of the earthquake is 3.7 (approx)

The magnitude of an earthquake is 3.7

Magnitude of an earthquake

The formula for calculating the magnitude of an earthquake is expressed as:

  • [tex]M =log\frac{I}{I_o}[/tex]

If  the magnitude of an earthquake is 5,011 times more intense than a standard earthquake, then

I = 5011Io

Substitute the given valuee

[tex]M =log\frac{5011I_o}{I_o}\\M = log5011\\M=3.70[/tex]

hence the magnitude of an earthquake is 3.7
