It was discovered pretty much when it happened. After the earthquake that triggered it occurred, authorities knew that a tsunami was likely. It reached parts of the Japanese coast less than an hour later. By then it was fairly obvious that a tsunami was occurring. The event occurred on March 11, 2011.
The Japanese named tsunamis.
The name means "harbor wave" coming from the fact that a tsunami can devastate coastal communities but people on boats at sea don't notice anything unusual as tsunamis don't achieve full height until they approach shore.
The water made the tsunami, isn't that weird? Half of the side of the sea floor goes up, and half of it stays in the same poss.
No one. A tsunamis is a natural outcome of an earthquake.
Nobody really "discovered" them - the waves have been around since the beginning of the world. Humans just observed them and started calling them names like "tsunami" or "tidal wave."
Tsunami is Japanese for harbor wave.
the Japanese!

The Earthquake occurred before the tsunami as it is what caused the tsunami.
tsunami's happen underwater and seismic waves happen on land or underground.
It is impossible to predict when a tsunami will happen until it is triggered.
