In mathematical terms it is a logarithmic scale. A difference of 1 represents a factor of 10.

Mr Richter has found a method to denote the magnitude of earthquake. The energy released for a particular earthquake to other may vary in terms of millions of times. Therefore he preferred logarithmic scale . That is when you want to write 1000 you can write as 10 Raised to the power of 3. Like that for writing one million you can write as 10 raised to the power 6. Please do not get confused in Richter scale. The ground shaking increases by ten fold for each Richter scale. But the energy released increases by 32 times for each Richter scale. Please visit my sites to have better idea on this subject.
