A tsunami makes a very shallow wave on the surface of the massive body of water as it propagates from the source. The vertical height of the propagated wave is very tall, as the body of water it travels through is very deep. It is a pressure wave caused by an underwater landslide at the epicenter. Underwater landslides can happen at any time; anywhere there is steep relief to shore. They are usually associated with an earthquake somewhere in the vicinity. As the wave travels through the body of water, it disperses or lengthens over distance in its direction of travel. This is why a tsunami does not devastate every shoreline perpendicular to the epicenter. As the wave reaches landfall, the ground gets shallower and the remainder of its height is exposed. Far enough away and it appears as slightly taller lapping waves for a short period. Close enough to the epicenter and the wave crests at considerable height; usually devastating since water weighs about eight pounds per gallon. Ten thousand gallons coming at you means eighty thousand pounds. Ten thousand gallons would be a narrow section of the broad wave making landfall. Thoroughly devastating. Extremely unfortunate.
the tsunami is gone when everything is dead and nothing is alive
it causes floods and can destroy buildings and can make people drown.
The usual measure of a tsunami is the height of the wave just as it reaches the beach.
Tsunami is the name of the wave (once known as a tidal wave) that is created by the sudden displacement of a large volume of sea water when an earthquake occurs on the sea floor. As the wave radiate outwards, it can often pass unnoticed by a nearby ship. When the wave reaches a shallow shore, the top of the wave continues at the same speed, while the bottom of the wave is slowed down by friction with the shallow sea floor. This causes the top to grow into a high wave that flows far into land. Damage and loss of life occur as the wave travels inland, picking up debris, then, as the wave retreats, the debris cause further damage as the wave retreats. There is often the case that a further wave(s) may still happen.
Tsunamis cause damage by two mechanisms: the smashing force of a wall of water travelling at high speed, and the destructive power of a large volume of water draining off the land and carrying all with it, even if the wave did not look large.

The tsunami destroyed many buildings and damaged nuclear reactors
They destroy homes and lives

no boats do not survive tsunami a tsunami can ruin everything

When getting word of a tsunami, a cruise ship will head out to the deepest part of the ocean she can reach. In deep water, a tsunami may only be a couple of feet or even inches high. It is not until the tsunami reaches shallow water that the wave reaches any appreciable height. In fact, a cruise ship in the middle of the ocean may be the safest place to be during a tsunami.

Fish cannot hide from a Tsunami. If a Tsunami comes, everything that lives in the sea is brought along with the wave onto the land.
