The major ones result from sub-sea earthquakes in subduction zones.
Others can be triggered by major undersea mud-slides or volcanic eruptions.
The 19C eruption of Krakatoa (or Krakatau) raised a gigantic wave that raced right round the world, obviously diminishing rapidly with distance but creating terrible havoc in the region. The cause was a gigantic final blast that may have been from the magma chamber collapsing and sea-water suddenly quenching a huge volume of very hot rock and lava. However, I'm not sure if this can be called a tsunami.

How do tsumanis form?
Tsunami's can be formed by earthquakes, volcanic eruptions, and rarely, a landslide or meteorite. When earthquakes start, most of the time, large areas on the ocean floor is suddenly elevated or subsided. All of the energy released from that pushes the water up and as more energy is released, more water comes up. And thus, it creates a tsunami. Volcanic eruptions can also cause earthquakes. Landslides are very rare. But when landslides do create a tsunami, it is referred to as a mega tsunami. And is a LOT more dangerous than a regular tsunami (not sure how much stronger). For a landslide to create a tsunami, you would need at least around 90 million tons of rock hitting the water simultaneously.
