Brace yourselves, east coast US, and 20 miles inland

[SailDesign]

Not to diss anyone's opinions, but...
Every action has an equal and opposite reaction. And tsunamis are an example of this. Drop a rock in the water and it sends out ripples. The energy contained in those ripples will remain constant under ideal conditions, but will drop over time in any real situation. In order for a 1/4 mile high wave (or even a 100-metre-high wave) to hit the whole East Coast, enough energy must be imparted at the source to create such a wave. I haven't crunched any numbers yet, but I'd be willing to bet (with my life, actually, since I live on a small island on the East Coast) that no one volcano in the Canaries can produce enough power to do this.
You not only have to create the initial wave, but then to send it over 3000 miles, and have it create a mega-wave over 2000 miles of coastline. Assuming the landslide that causes this is over, say 5 miles of coast, then each mile of slide must be able to power a giant wave that will cover 400 miles of coast on the other side.
I call "Improbable" at best, but will look at the numbers.

look at the numbers first plz

the most likely scenario
a catastrophic failure of La Palma west flank, drops 150 to 500 km3 of rock into the sea. Using a geologically reasonable estimate of landslide motion, we model tsunami waves produced by such a collapse. Waves generated by the run-out of a 500 km3 (150 km3) slide block at 100 m/s could transit the entire Atlantic Basin and arrive on the coasts of the Americas with 10-25 f (3-8 m) height.

why does this matter ? it will be the entire east coast where there are ZERO tsunami walls in place.

it is probably not going to happen, or it will slide incrementally and not produce large waves, but
the possibility exists nonetheless and the chance is increased lately due to volcanic activity

the base of the island is 4000 meters below sea level. If that full flank also blows out in a huge eruption
and lateral collapse, similar to Mt St Helens (where the entire side of the volcano slid outward and downhill),
there will be a tsunami far larger than the estimate above. Will is happen ? probably not, but the chance is not zero.

Glad to see a more reasonable estimate of wave height. It is the 1/4-mile high wave that I refuse to believe. The amount of energy required to produce that over that much coastline is just unimaginable. Producing a 25-foot wave is still a staggering thought, but is imaginable.
I'm glad someone else knows how to calculate this stuff, because what I have been able to find really doesn't make it look simple.

Dood - do you model tsunami waves, or are you an IT security consultant? Please make up your mind.
I don't honestly care which, but you are not sounding particularly together here. If you model tsunamis, that's fine - but if you are an IT expert, please don't pretend to be able to model things like that in the real world. I'm only a yacht designer/engineer. I don't pretend to have the naus to do sh!t like that, although I do understand wave energy spectral calcs and all that they imply.

I do a lot.

here is who did the number crunching.

and I am NOT an IT -consultant-. I work on protecting information assets and
to give you a clue I work with everything from cryptographic algorithms, behavior analysis,
fractal mathematics, predictive analytics, biometrics, and how to keep cereal crispy.
I do not consult. I actually fix problems. Problems can have 1 element or 1000, and can be
anything you imagine. I have an IQ I am happy with and I seem to have an ability to
grasp any new subject or task with relative ease (relative to others in the same room,
working on the same issues).

I am no better at anything, than any other person. But I do my job well, that is all I can say.

Yes we have a master Jedi in our forum there for my knowledge or anyone's is worth crap.

Yup, made sense long time ago.

Haven't you heard? We have a Jedi master here man the force is so strong in this one.

how long it took you to google it?
Is fixing problems all you do?, the muffler bearings are making a grinding noise on the tranny can you tell me what's the problem!?
Do your self a favor stop bragging about how smart and intellectual and what you do and can't do it's not gonna get you anywhere here. Besides we got CTScott here for all that and he does not brag about anything helps and moves on.

Somehow that's not compatible with the aftermarket headlight fluid I'm running. It's also giving my tire springs some issues.

This.
