To get rid of our log here, we need to take both sides as the exponent of 10. The left hand side becomes 10 to the 1.1, and on the right hand side that will just leave us with J over C. Now let’s use our calculator. 10 to the 1.1 is equal to 12.589 and so on, or rounded, about 12.6. So what does this mean? Well, that means that the intensity of the Japenese earthquake was about 12.6 times greater than the worst California recorded earthquake.
