What is the magnitude of an earthquake that is 35 more times intense than a standard earthquake

natita [175]

The magnitude of an earthquake that is 35 more times intense than a standard earthquake is 1.5

Step-by-step explanation:

Let

I be the intensity for which we have to find magnitude

S is the standard intensity of earthquake

And

M is the magnitude

The intensity of standard earthquake is 10.

$35\ times\ of\ 10 = 35*350 =350\\I=350$

The formula for magnitude is:

$M= log \frac{I}{S}\\Putting\ values\\M= log \frac{350}{10}\\M = log\ 35\\M = 1.544\\M= 1.5$

The magnitude of an earthquake that is 35 more times intense than a standard earthquake is 1.5
