Solve the problem.
-An earthquake had an intensity $10 ^ { 4.4 }$ times more powerful than a reference level earthquake, or $104.4 \cdot \mathrm { I } _ { 0 }$. What was the magnitude of this earthquake on the Richter scale? $\mathrm { R } = \log _ { 10 } \left( \mathrm { I } / \mathrm { I } _ { 0 } \right)$.
A) $14.4$
B) $5.6$
C) $4.4$
D) $10.1$

Quizplus · Accepted Answer

The magnitude on the Richter scale is calculated as $ R = \log_{10} (I/I_0) $. Given $ I = 10^{4.4} \cdot I_0 $, we have $ R = \log_{10} (10^{4.4}) = 4.4 $.
