This is an example of how we must be pretty careful when drawing firm conclusions in science as things are not always the way they initially appear to be.
The article is also an example of how journalists love to over dramatise things.
When underwater divers discovered what looked like paved floors, courtyards and colonnades, they thought they had found the ruins of a long-forgotten civilization that perished when tidal waves hit the shores of the Greek holiday island Zakynthos.
If a city is found under water, it suggests that the land is sinking, or the sea rose. Typically this happens slowly. Occasionally it might be more dramatic with an earthquake or something. But 'tidal wave' is not one of the reasonable scenarios.
