Is a magnitude 10 the top of the Richter scale?

While the media often refers to the Richter scale as being on a scale of 1 to 10, there is no upper limit, even though the strongest quakes are not as high as 10. It is incorrect to assume that a 7 is on a scale of 1 to 10 because the magnitudes are based on the energy released and it is a logarithmic scale.
