1

Why does the ground shake?

Plates try to push past each other, which builds up pressure

2

What happens when the pressure builds up too much?

That pressure is suddenly released – a release of energy happens along a fault

3

How does the energy travel?

The energy travels out in all direction as earthquake waves

4

How is energy measured and what is it measured using?

Measured as magnitude using a seismometer

5

How do tsunamis travel?

Through a jolt upwards causing a displacement of water travelling in all directions

6

What affects the size of the tsunami?

The frequency of movement - Long period means pressure builds up, eventual movement will be greater, generating much more energy

7

Are shallow epicenters weaker than deep ones?

No

8

Where was the worlds largest earthquake?

Valdivia-Puerto Montt, Chile(1960)

9

Which coast was the 2011 Japan earthquake on?

Coast of Honshu

10

Why do waves from a deep earthquake spread quickly?

Deeper rocks are under high pressure and rigid so wave energy can travel from particle to particle fatser

11

Which countries relied on components from Japan and were affected by the disaster?

Singapore, Thailand and UK

12

Which power plant had the cooling system stop working as a result of the tsunami?

Fukushima

13

Which countries benefitted from the damage to Japan's nuclear industry?

Qatar, UAE and Kuwait

14
