When the Gilbert Inlet suffered an earthquake in 1958, a 30 million cubic meter area of rock slipped into the Lituya Bay. The resulting tsunami was
1720 feet tall. The Hilina Slump is 5,000 cubic MILES of land.
Thanks for the reminder of that (was it the History or Science Channel) installment Zaphod. It was shocking even in the tank simulation. Also had the
dubious discomfort of watching the father-and-son firsthand account of that one on the fishing launch.. if we're on the same page, it was like a half
mountain dumping into the blind end of a short fjord. Trees scrubbed off the valley walls 120 or 150 feet high, OMG... duck and hold your nose.
But this is really as bad as it gets, being the economy sized real time event just like
the simulation-- when there's nowhere but straight
out in a plane wave and nowhere else to go. Just the same--- those poor guys.
Might not be as bad over a whole ocean's distance away though.
If you think of it like a sound wave, circular in form on the open water and expanding all the time, the tsunami's intensity decreases over distance
due to the area effected. 6dB rule; so as the wave fans out its destructive potential (height and force) decreases as the square of the distance.
It's why N Oz didn't get it near as badly as Indonesia, because Jakarta were about ringside.
I'm personally too close to the New Madrid and stuck in a blue area on that 2015 Navy map to worry over here. I'm swamped like a box elder bug in a
car wash... like 45-60 miles from beachfront property LOL.
This thread may be drifting a little and I apologisze for my end, but there IS an old friend who whistled off a CDR from Hawaii: his last three of
five hitches doing CG chopper aircraft commander, rescue/recovery. "Pumice blasts turbine parts, chokes compressors and in general makes you
plummet." I'll take Dallas' word for it... even if at the time it sounded Python-y.
I never asked him about autorotation through a 0-0 fog of spunky igneous rock dust: but I'm also glad he never brought it up.
