If the relative intensity of an earthquake is 14490, find the magnitude.

Answer 1

The magnitude of an earthquake can be calculated using the following formula:

magnitude = (2/3) * log10(relative intensity) - 1.76

Plugging in the given value of relative intensity of 14490, we get:

magnitude = (2/3) * log10(14490) - 1.76

magnitude ≈ 5.6

Therefore, the magnitude of the earthquake is 5.6.
