I repeatedly have to correct this belief. In a sense, magnitude involves steps of 10 because every increase of one magnitude represents a tenfold amplification of the ground motion. But there is no 'scale of 10' in the sense of an upper limit.

Baseball calls it a curve ball for a reason: you just don't know where some pitches will land. Your ace could get injured. Your golden glover could err. Your team could sit through a rain delay. Your manager could get ejected. Your bench must be broad and deep enough to overcome.
