Earthquakes

1. Earthquakes Learning Objective: To define the main key words associated with earthquakes and explain how we can measure their power EBIYC: to apply the Richter Scale to past examples and give justification for its magnitude

2. 2) Use the words to create your own definition of ‘Earthquake’ or unjumble the words below Earthquakes are the result of a build up of stress…. sudden release within the Earth’s crust and a of energy that creates seismic waves 1) Create a list of words you associate with ‘Earthquake’ sudden release Earth’s crust and a

3. Earthquakes are the result of a… …build up of stress within the Earth’s crust and a sudden release of energy that creates seismic waves. Which plate boundaries do we find earthquakes at?

4. Where the plates get stuck Shockwaves travel through ground Pressure is released in a jolt (sudden movement) Pressure builds up

5. What are the focus and epicentre?

6. What are the focus and epicentre?

7. North American plate Pacific plate California sits on a conservative plate boundary and are currently waiting for ‘the big one!’

8. Earthquakes… Draw your own diagram of an earthquake on your white board Annotate your diagram with definitions of the focus, epicentre and fault. Why do you think the location of the focus is important?

9. How can we measure earthquakes?

10. Richter Scale

11. Can you predict the magnitude for the following past earthquakes? Predict the Magnitude… You will need to be able to justify your prediction.

12. $20bn in damage 69,200 deaths Sichuan earthquake, China (2008)

13. $0 in damage 0 deaths Cornwall earthquake, UK (2011)

14. 4 million homeless 86,000 deaths Kashmir earthquake, Pakistan (2005)

15. 474 properties damaged 0 deaths Folkestone earthquake (2007)

16. 0 deaths 83 made homeless California earthquake, USA (2014)

17. $9.9bn in damage 300,000 deaths Boxing Day Tsunami (2004)

18. 8,583 deaths $5 billion damage Nepal earthquake (2015)

19. Nepal earthquake April 2015

20. The overall impact (destruction/death/injury) of an earthquake relies on a variety of factors… Let’s discuss each one! Why might they affect the level of destruction? Time of day HIC/LIC Emergency procedures Education Quality of housing Depth of focus Population density Residential area Magnitude

21. Homework 1) Rank your factors in order of importance You can either rank them as a line (most to least), a pyramid or diamond Be prepared to justify your answers to the class Time of day HIC/LIC Emergency procedures Education Quality of housing Depth of focus Population density Residential area Magnitude
