The Tsunami waves got bigger (or higher) as they approach land because the swells of water rise up as the seafloor gets shallower.
They start as an underwater wave (see related question below for what causes the wave) usually very deep on the floor of the ocean and moves (they can move in speeds up to hundreds of miles an hour) outward from the initiation point. If they move toward land, as the water gets more shallow with the increased height of the ocean floor in a harbor or coastal area, the wave gets higher as the sea floor gets closer to the water's surface. They have enough force and speed that they do not stop or get smaller at that point, but continue to move into water that is more and more shallow and get bigger and bigger (taller) and rise out of the water, since there is no place to go but up.
Tsunamis are created by earth quakes and they get bigger because they just pick up the water and drag it along as they move!
as the water becomes more shallow the wave becomes bigger then once it peaks, its usually on land and collapses
Tsunamis that are triggered by volcanic eruptions
Tsunamis cannot be prevented.
Wind does not affect tsunamis.
air pushes the tide ; making it bigger
no way to be sure there are hundreds of small tsunamis every year, but they aren't much bigger than the average wave by the time they reach the coast.
Bigger tides, more earthquakes and tsunamis etc.

yes because tsunami can grow bigger than a volcano eruption
the tsunami will get bigger every second and all the boats and ships will be destroyed because tsunamis are as strong as 60 hurricanes.

They cause tsunamis
No, it´s the opposite. boxing day tsunami was one of the biggest tsunamis in history
Unfortunately there is nothing we can do to prevent tsunamis.
