TRANSCRIPT
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)

What did the 22nd Feb earthquake measure on the Mercalli scale?
Complete the Mercalli Scale matching game (in groups) to help you…
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
Richter vs Mercalli!
