Is it possible for a Tsunami to occur in a (Great) Lake?

Answer 1

actually a giant wave like a Tsunami can happen in one for the Great Lakes.
Tsunamis or great waves can form in various ways, but the key is displacement of a large volume of water. IE earthquake. meteor impact, massive land slide, volcanic eruption and so on.

So if for some reason a large enough displacement took place a giant wave could be created

Is it likely to happen. No. Your chances very very slim that it would.

Answer 2

I think it cannot happen.There is no possibility of existance of any fault(boundary between any two tectonic plates under the earth's surface) under a big lake.If any fault were to be there, earthquakes would have occured many times during the long history of the earth(ie, millions of years)over that place and the lake would have vanished due to crack created by the earthquakes.
So, the very fact that big lakes exist for so many years confirms the fact that there is no fault underneath and there is no possibility of earthquake under the lake and hence no tsunami.
But small ponds and lakes near the sea shore are likely to be slightly affected by tsunami originated from a far of place.During the recent tsunami originated from Indonesia,there were reports of water level raising(and falling later) in ponds and lakes near the shores(eastern sea shore) of Penisular India probably due to pushing of underground water by tsunami waves.
