The magnitude, M, of an earthquake is defined to be M=log I/S, where I is the intensity of the earthquake (measured by the ampli

GarryVolchara [31]

Answer:

Step-by-step explanation:

Magnitude $M$ of an earthquake is defined as $M=log\text{ }\frac{I}{S}$ . Here $I$ is the Intensity of the earthquake and $S$ is the intensity of standard earthquake.

We have an earthquake that is 10 times more intense than a standard earthquake. Let us denote the intensity of the earthquake as $I$ .

10 times more intense than standard earthquake ⇒ $I=10S$

Magnitude of the earthquake = $M\text{ = }log\text{ }\dfrac{I}{S}\text{ = }log\text{ }\dfrac{10S}{S}\text{ = }log\text{ }10\text{ = }log_{10}\text{ }10\text{ = }1$
