Earthquakes are measured on 2 different scales
The Richter Scale – measures the magnitude of the earthquake on a scale of 1 – 10. Each point on the scale is:
10x bigger in size (or amplitude)30x the energy released
The Mercalli Scale – measures the damage done at a particular location on a scale I – XII
I (not felt) – XII (total destruction)

Richter Scale
How much bigger is the amplitude of a magnitude 4.0 earthquake compared to a magnitude 8.0 earthquake?
10 x 10 x 10 x 10 = 10,000 times bigger
How much more energy is released?
30 x 30 x 30 x 30 = 810,000 times the energy
