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 whiteboards1) What do you think happened in the 30 minutes before the clip2) 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 knowA 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 sweetsThe effect of this whole was toothacheMy response was to get a filling from my dentist(And to eat less sweets in the future)
