Exactly where it started: A seismologist says that tsunami similar to
this one seem to hit Japan about once in 1,000 years. You seem to have
problems understanding that it is the size and intensity of this
tsunami that makes it a one in 1,000 year event, not simply that it was
a tsunami.


But the point being made here is that it was not a 1 in a 1000 year
event. A few decades before the plant was built a tsunami of greater
height was recorded and the one previous to that was 30metres

Something of a similar or greater magnitude actually happening in the
same general area every couple of decades or so makes the likely hood of
it happening within the life of the plant very real.
