One way to help make sense of it is to think of each number in the scale as how many zeros it has.
The Richter Scale for measuring earthquakes is logarithmic, so an earthquake that measures 8.0 on the Richter Scale is ten times more powerful than one measuring 7.0.
10 = 1,000,000,000
9 = 100,000,000
8 = 10,000,000
7 = 1,000,000
6 = 100,000
5 = 10,000
4 – 1,000
3 – 100
2 = 10
1 = 1
