Incidentally, the usual designation of the magnitude scale to my name does less than justice to the great part that Dr. Gutenberg played in extending the scale to apply to earthquakes in all parts of the world.
By moving them vertically, a representative mean curve could be formed, and individual events were then characterized by individual logarithmic differences from the standard curve.
If one introduces the concept of energy of an earthquake then that is a theoretically derived quantity.
I was lucky because logarithmic plots are a device of the devil.
Logarithmic plots are a device of the devil.
Don't wait for extraordinary circumstance to do good; try to use ordinary situations.
