Why did the Tsunami happen?

Sudden shifting of continental plates causes earthquakes, forcing sea water above, to rise

As they collide the Australian plate is pushed up and over the Pacific plate. This causes buckling of the Earth’s crust, building mountains and triggering earthquakes

As waves near land, they slow to a 45km/hr but are squeezed upwards, increasing in height
