Answer:
Explanation:
The relationship between magnitude (M) and intensity (I) of an earthquake is given by:
I ~ 10^(1.5M + 4.8)
We can use this relationship to compare the intensities of the two earthquakes:
I1/I2 = (10^(1.5M1 + 4.8))/(10^(1.5M2 + 4.8))
= 10^(1.5(M1 - M2))
Substituting the given magnitudes, we get:
I1/I2 = 10^(1.5(8.6 - 8.2))
= 10^(1.5(0.4))
≈ 2.24
Therefore, the intensity of the first earthquake was approximately 2.24 times greater than the intensity of the second earthquake.
