Multiple Choice

Use the formula R $\mathrm { R } = \log \left( \frac { \mathrm { I } } { \mathrm { I } _ { 0 } } \right)$ , where the magnitude of an earthquake on the Richter scale is based on I, the measurement of a seismic wave, and I0, the measurement of a seismic wave of a level zero earthquake with the
Same epicenter. An earthquake was recorded which was 2,511,886 times more powerful than a reference level
Zero earthquake. What is the magnitude of this earthquake? (Round to the nearest tenth.)

A) 0.6
