What's the plan for today?

1. START: C7.2: The Great East Japan Disaster
   

GOALS OF C7.2

1. You can explain the words epicentre, hypocentre, Richter scale and seismologist (GG 73 + GG 74).
   
2. You can explain how the Richter scale is calculated (GG 74).
   
3. You can explain in 4 steps how a tsunami works (GG 76 ).
   
4. You can name the 5 scale levels and know their meaning (GG 7).
   
5. You can name 4 consequences of the tsunami in Japan in 2011.

C7.2: The Great East Japan Disaster

On Friday 11 March 2011, the north-east of Japan was hit by a heavy earthquake. The quake caused a tsunami that claimed many victims and caused a lot of damage.

You can explain how a earthquake occurs.

Earth plates slide past each other. Because this is difficult, the tension between the plates is built up. If there is too much tension, the plates will shoot to discharge the tension.

You can name the difference between a epi- and a hypocentre.

Earthquakes start in the Earth’s crust. The deepest point is called the hypocentre. The point on the Earth’s surface right above the hypocentre is called the epicentre. That is where you feel the worst tremors.

You can name how the Richter scale works.

"Scale for measuring the force of an earthquake."

How a tsunami is formed

G 7  Switching scale level

local scale: local 

regional scale: part of a country, province or territory 

national scale: country ,

continental scale: continent ,                          Zooming in

global scale: the world .                                      

                                                                                        Zooming out

Look at the next movie.
