Makes sense to me. Those 9.0 earthquakes and tsunami's happen every few thousand years, you know. You can't be too careful.
The ancestors of current Japanese had placed cairns of rocks, obelisks, and other warnings at the high water marks of PRIOR tsunamis - centuries, not millenia, earlier; historic times - essentially warning future generations that they shouldn't build lower down the slopes. Their far smarter and wiser descendants laughed at the quaint ways of their primitive ancestors and ignored the warnings - with predictable results.
It will be interesting to see how Japan suffers with rolling brownouts and blackouts, industry shut downs, and the cost to their economy of importing even more fuel - this just may be a case of national
hara-kiri. (And BHO is more likely too take it as an
example, rather than a warning.
