Answer 1

Answer:

The intensity of the first earthquake is 6.31 times the second one

Step-by-step explanation:

The given formulae is M=log($\frac{I}{S}$)

Here for both the earthquakes the value of S is same.

Let the Intensity of the first earthquake be I1 and the second be I2.

Given M1=7.5

M2=6.7

Now  M1=log($\frac{I1}{S}$)------1

M2=log($\frac{I2}{S}$)-----2

Now subtract 1 and 2 we get

M1-M2=log($\frac{I1}{I2}$)

I1/I2=$10^{M1-M2}$

I1=I2($10^{0.8}$

I1=I2*6.31
