Charles F. Richter proposed his earthquake-measuring scale 180 years after this earthquake. Measuring the 1755 quake's scale requires an educated guess. And seismologists guesstimate it to be in the 8.0-9.0 range, give or take a few murder-tenths. We know the devastating shaking reached Morocco. We know further tsunami waves reached Ireland. The quake's psychological toll dominates Voltaire's Candide.
In America, we call that kind of catastrophe "an act of God." Why? Is it because we are all devout Christians? (Survey says [red X and buzzer sound].) Is it because insurance companies literally call it "an act of God" when they "adjust" your disaster benefits? Is it because God is culpable and the authorities plan to arrest Him?
