What distinguishes a tsunami from other types of ocean waves?

• The wave energy of tsunamis increases as the water depth decreases.

• A tsunami forms when a large volume of water is suddenly displaced up or down.

• A tsunami is caused by the disruption of deep ocean currents by volcanic eruptions.

• The wave height of a tsunami is much lower in the center of the ocean than it is near shore.
