Perhaps you would be interested to know the largest recorded tsunami was 530 metres, in a fiord in Alaska, in ...1958. Bob


How big was the biggest tsunami ever? ? Ask an Expert (ABC Science)

the answer to that question is about as simple as "how long is a bit o string" Invariably the most appropraite answr is "too short"

you need resolution on a bunch of variable data on very short notie and some very quick seat of the pants math magic the nuts and bolts of your variabels being

where idi it start,?
how big did it start?
which way is the majority of the wave force pushing?
whats the topography in that direction?
whats its starting speed and whats it current speed?
whats the tide doing?
whats the water flow in the area?

and when you have all of that you have the ability to swing pretty good guess at it.

theres some ancedotal evidence that some tsunamis have been tracked over sosus nets and radar tracks from ships seismology is getting better at getting the start point.

I wouldnt mind betting that with the right sotr of data filtering and networking you could use just about everything that floats and has radar/depth sounder to up the availabl info so the prediction timescan get fster.

I have a very vgue recolection of someone coming up with a chin of bouys that was mentto be dropped off along the most likely lines of ndngers and if they reacted a certain way after they picked up a siesmology warning from another bouy which would give you a short notice but better than none warning of speed direction and intensity.

Wonder what came of it.

Open the first link, all is revealed, Bob

I was of the belief Moreton, Stradbroke & Bribie islands would give some protection in the event of a Tsunami, not so. Bob
