Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.

VIDEO ANSWER: The notes standard is quick to the magnitude and so now we'll say that captain twonette minus not of the minus the 10, not a right to m, becomes log 10. 10 is minus log 10 points. m minus m becomes log 10 minus log 10. Don't log over10. Each time the magnitude increases by one unit, the measured ground motion becomes 10 times larger. The Richter Scale.
