It is called a tsunami
a tsunami is a tidal wave caused by an underwater earthquake :]
It is a tsunami.
what is a warning sign of a tsunami
Obviously, the earthquake happens first and then tsunami follows.
The earthquake was first and caused the tsunami, like when you throw a stone into a pond first and then the ripples go out.
The effect we now call tsunami has been happening since there have been oceans on the planet Earth (billions of years). There was no "First Tsunami"; the Japanese have been calling the effect 'tsunami' for many centuries.
None after the tsunami

the first tsunami was in 1001 it was 200m high
Do you mean the first wave of the recent Japanese tsunami? If so, the first wave struck late on Thursday night.
It depends on what exactly you mean by predictable. If you mean is it possible to predict when a tsunami will happen, then the answer is negative. Tsunami are most commonly caused by seismic activity of tectonic plates, which creates a sudden, violent displacement of water. This means that to predict a tsunami, one must first be able to predict the earthquake, which, at the present time, is not possible. If you mean if it is possible to predict the behaviour of a tsunami, then the answer is yes. Tsunami follow set equations of wave behaviour, and therefore elements such as speed, height, wave period etc can be found and modelled.
Tsunami, water damage
It hit Sumatra first, an Indonesian island.
