Answer:

Magnitude of the aftershock = 0.3

Explanation:

Based on the information in the problem, an expression can be written that relates the magnitude of the earthquake (M₁) with the magnitude of the aftershock (M₂):

M₁ = 25M₂

We can then solve for M₂ and substitute in the values in the problem:

M₂ = M₁ / 25 = 6.3 / 25 = 0.3
