The magnitude formula for the Richter scale is where E is the energy released by the earthquake

Question:

The magnitude formula for the Richter scale is

where E is the energy released by the earthquake (in joules), and E₀ = 10^4.4 joules is the energy released by a small reference earthquake used as a standard of measurement.

a. The 1906 San Francisco earthquake released approximately 5.96 × 10¹⁶ joules of energy. What was its magnitude on the Richter scale?

b. How much energy was released by the Fukushima, Japan, earthquake of 2011, which measured 9.0 on the Richter scale?
