The Japan Tsunami...What it caused...

What is a Tsunami?

• A Tsunami is a chain of quick moving waves.• A Tsunami is produced when two of the world’s

plates slip away from each other triggering an Earthquake.

• The Earthquake triggers the sea and a Tsunami Wave is produced.

Why did it happen?

• The tremors were the result of a violent uplift of the sea floor 80 miles off the coast of Sendai, where the Pacific plate slides beneath the plate Japan sits on.

• Tens of miles of crust shook along the trench where the plates meet.

• The earthquake occurred at the relatively shallow depth of 15 miles, meaning much of its energy was released at the seafloor.

It was the most powerful...
