Earthquakes and tsunamis: Honshu, Japan, 2011

I can describe and explain the causes and consequences of the earthquake in Honshu, Japan, 2011.

Lesson details

Key learning points

  1. The earthquake was the fifth most powerful earthquake of all time.
  2. The epicentre was on the sea bed, 70km east of the Honshu coast.
  3. The resulting tsunami wave was 40 metres high and came inland for 10km.
  4. More than 350,000 buildings collapsed or were damaged and over 15,000 people died.

Common misconception

Tsunamis are random events caused by severe weather.

Tsunamis are not random events but are caused by tectonic plate movement underneath the ocean.

Keywords

  • Tsunami - Tsunamis are huge waves caused by earthquakes or volcanic eruptions under the sea.

  • Pacific plate - The Pacific plate is the largest tectonic plate. It is situated between North and South America to the east, and Australia and New Zealand to the west.

  • North American plate - The North American plate is the tectonic plate that includes most of North America.

  • Impact - To have an impact is to have an effect on someone or something.

A mini tsunami can be made using a tray, sand, a whiteboard and water. Place sand at one end of the tray and fill the rest of the tray with water. Use the whiteboard to quickly push the water towards the sand. Students will see the tsunami hit the sand (beach) and water (sea) recede.
