Just to clarify what I said above, I'm not singling out the PNW's Powers That Be as if they were the only ones who have this "we have plenty of
time" or "it won't happen on my watch" kind of attitude. I've just witnessed the results of an identical mindset here -- and our Powers That Be
can't say "we never imagined it would happen".
Back in August 2002, we had devastating floods. Statistically classified as a 1-in-500-year event, the floods caused somewhere around 3 to 4 billion
dollars in damage. The damage just in Prague was probably around one billion dollars altogether. That's a huge amount of money in a country where the
average wage was (at the time) not even $1,000 a month and our population was only ten million people.
Afterwards, plans were drawn up to protect many areas from future floods by the use of various barriers, both permanent (levee and/or concrete wall)
and temporary (portable, braced metal panel).
Eleven years later, we get another flood. While it wasn't as big as the last one it was still well over a 1-in-100-year event in many areas. In most
places where the permanent flood defences had been built and temporary barriers were set up, the damage was vastly reduced. This was especially so in
Prague: the few hundred million dollars the city and state invested prevented damage that would have been several times that. There was still some
damage, but at least we didn't have whole sections of our capital's downtown flooded like we did last time.
However, some areas in this country had permanent flood barriers that were just not high enough and only a week or so ago, they got overtopped or
simply failed -- due to a flood that was smaller than the last one! And in other places they hadn't even started building their defences yet
-- even after 11 years.
The damage to those places is immense and will cost many times more than all the proper-sized defences would have cost. And I guarantee that even if
we wait (hopefully) another decade or more until the next big flood, there will still be towns that will not be protected.
So, I appreciate the problem. But the fact remains: the PNW region is vastly under-prepared. And unlike a "normal" flood that can take hours or days
to move down swollen rivers, giving many enough time to pack up possessions and leave, a tsunami from a major quake can arrive inside half an hour.
We saw what happened in Japan. Yes, in many places their huge tsunami-defence walls were overtopped or even destroyed. But they still gave many people
time to flee to high ground, and doubtless saved thousands of lives.
We in this little forum know that the PNW can have a tsunami just as big as Japan's, after a quake also just as huge. And the authorities know, too.
They've been told as much by top experts, in great detail.
So now, they have signs up along many of the coastal regions to show people which way to run if a tsunami is coming. Well, at least that's
something.
Those signs are most useful if a tsunami happens along in the daytime when most people are up and about. The last one (on Jan 26, 1700) hit sometime
after 9pm, when it was full dark and also the middle of winter -- and disaster planners should always plan for the worst scenario, not the most
convenient one. Putting up signs is good, but it's not enough. They need defence walls and escape towers. Lots of them. I know some towers are being
built, but more needs to be done.
I hope they have at least 20 years to get things done, because I doubt they're going to be somewhere near Japan's standard in less time than that.
Not unless there is a major policy shift at both state and federal level and defensive measures to save lives get the large amounts of money they
really need.
