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) Do now : copy Monday, June 27, 2022

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
