Did you know...
... that today is National Richter Scale Day? Today, we honor American seismologist and physicist Charles Richter, born near Hamilton, Ohio, on this date in 1900. Richter is most famous as the creator of the Richter magnitude scale that, until the development of the moment magnitude scale in 1979, quantified the size of earthquakes.
