That is precisely what engineering means.
The plants should have been hardened against any conceivable tsunami/earthquake?
What about the schools and homes- 1000s of people died in those.
Surely all primary schools should be proof against a magnitude 10 earth quake?
Here on the other side of the same fault zone we spend only a few million $$ bolting classroom bookcases to walls.
If society had priorities then all the children would be protected by schools built deep underground in bunkers, and all the old peoples homes, and all the hospitals etc etc - in fact nobody would be allowed to live within 100km of the pacific ocean
