Solve the problem.
-An earthquake was recorded with an intensity which was $1,258,925$ times more powerful than a reference level earthquake, or $1,258,925 \cdot \mathrm { I } 0$. What is the magnitude of this earthquake on the Richter scale (rounded to the nearest tenth)? Intensity on the Richter scale is $\log _ { 10 } ( \mathrm { I } / \mathrm { I } 0 )$.
A) $14.0$
B) $0.6$
C) $6.1$
D) $5.1$

Question

Quizplus · Accepted Answer

The magnitude on the Richter scale is calculated using the formula $\log_{10}(I/I_0)$, where $I$ is the intensity of the earthquake and $I_0$ is the reference level intensity. Given $I = 1,258,925 \cdot I_0$, the magnitude is $\log_{10}(1,258,925) \approx 6.1$.
