“The sheer amount of energy generated is difficult to comprehend. Although the crust probably shifted by only a centimeter, the incredible density and gravity made it well beyond anything humans have ever experienced. The quake would have registered a 32 on the Richter scale — mind you, the largest earthquake ever recorded was about a 9, and it’s a logarithmic scale. In just 200 milliseconds — a fifth of a second — the eruption gave off as much energy as the Sun does in a quarter of a million years.” - Anthony Citrano
