I'm sorry, but is it that surprising to expect that, over the course of a decade, that an area prone to tsunamis would have one?
IMHO, it took a catastrophe for people to accept a relative certainty.
In other words, it was bound to happen, but until it did, the average person will choose to live in denial.
Can you cite another remotely similar case where
a quality geologist doing quality research
went so far out of his way
to warn a population/geographic area
of a serious quake hazard being looming in the relatively short term
which was followed
within a relatively few months--literally a few months--
by a very devastating; shockingly devastating quake markedly uncommon in our times?
WHY IS IT SO HARD to give this guy his considerably above average due?
SHEESH!
