8.0+ earthquakes are quite unique, there's on average only one 8.0+ earthquake per year. [1]

I can't even comprehend the amount of energy required for an 8.0M earthquake.

From searching it seems an 8.0M earthquake is equivalent to a nuclear explosion of 6,270,000 tons of TNT but a 7.0M is 199,000 tons of TNT.
