I have not heard of any recent severe earthquakes that would trigger this. True there are after shocks as is often the case with these events, but none so powerful or of the right kind to trigger a tsunami. The tsunami that hit Japan was caused when the whole country lurched suddenly 13 feet to the east and 2 feet downward.
Will there be another tsunami? Yes, without a doubt; but as to the timing, that depends on how fast the internal changes inside the earth are transferred to the crust and where this occurs.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
