Tsunamis
The Syllabus says: Tsunamis are a
specific secondary effect and can
have devastating effects in coastal
areas.
This will be studied through a
“case study of a tsunami – its
cause, effects and responses.”
Mr Anderson says: Tsunamis
are caused by earthquakes
under the sea. Therefore they
are NOT tidal waves. Tsunami
is a Japanese word meaning
“harbour wave”
STARTER, watch this trailer: (see notes) on your
whiteboards
1) What do you think happened in the 30
minutes before the clip
2) what happened in the 24 hours after?
Challenge: What happened in the next
month?
The Asian Tsunami of 2004 is also called the Boxing Day Tsunami. It killed over 230,000
people (over 5 times the whole population of Salisbury) It was caused by a 9.1
Earthquake at the boundary of the Indian and Eurasian plates)
30 minutes before
The
tsunami
24 hours after
Over the next 6
months
The exam board says you need to know
A case study of a tsunami – its causes, effects and
responses to it.
Now categorise the 20 statements in
the envelope into either: Can you
finish before the music does?
• Description and causes of the
tsunami
• Effects
• Responses
Too easy? Finished?
What effects could you
add from the trailer?
The whole in my tooth was
caused by too many sweets
The effect of this whole was
toothache
My response was to get a filling
from my dentist
(And to eat less sweets in the
future)

Do C/D and begin to 1) describe the links between short term and
long term effects and 2) explain the impacts of the responses to
the Asian Tsunami
(B/A)
Do C/B and fully describe how the effects interact to create long
