If you are into the science behind large waves (which were thought by scientist not to exist no matter how many times mariners told them) then this Horizon is excellent.

Very choppy!

Love that stuff Stokie! tHink I might have seen that one, but its right up there with mega tsunamis in the nerd stakes imo.
Has anyone ever looked at their own postings for last day or so? Oh my... so sorry. Was Ullaa

Me too. I only skimmed the end of that but I didn't see much in the way of hypotheses for causes?
https://en.wikipedia.org/wiki/Rogue_wave looks interesting too... 'Rogue waves can occur in media other than water. They appear to be ubiquitous in nature and have also been reported in liquid helium, in quantum mechanics,[3] in nonlinear optics and in microwave cavities, in Bose—Einstein condensation,[4] in heat and diffusion[5] and in finance.[6] Recent research has focused on optical rogue waves which facilitate the study of the phenomenon in the laboratory.'
I propose that the cause in all of these media might be a jolt in the space-time continuum, possibly caused by a dramatic spike in demand for electricity when someone posts something about a potential takeover on here.

I like your theory.
From memory, the theory at the time was that all sea waves could be explained by the linear model and that a wave of ~30m would only happen once every 1000 years. A 28m wave then hit an oil platform in the North Sea and everyone suddenly took interest because that really shouldn't happen if the theory was sound.
The proposal was to use the non-linear Schrodinger equation which they believed showed that a wave could start "stealing" energy from the two adjacent waves and thus have excess energy outside the linear model and grow to a massive size.
This is bad because not only is the wave large but the troughs either size are very deep so such a wave would crash into the centre of the ships rather than the bow and because they aren't designed for that they snap in half and sink.
In a month using a satellite they found something like 100 waves over 20m which shouldn't be there according to the accepted model.
A quick Google shows that things have moved on, this is very interesting:

Looks like they are trying to argue that the principle can be applied to prices that suddenly deviate outside the expected trend or where there is a spike in volatility calibration. As you said originally, the causation would seem to be very different even if the plots look similar.

Mathematicians don't see things quite like scientists do.
Within the limits of their field it is all relevant. They are more concerned with the patterns than the reasoning behind them, I think. If the modelling works, what does it matter what cause it? Indeed, maybe there is a pattern within the apparent randomness that is similar in how it builds.

They also found that rogue troughs/holes were a thing too. Both having the potential to snap ships by forcing too much of the ship out of the water and the weight becoming too much as they are designed to be in the water.
There was also evidence to suggest these occurrences happen in certain places far more regularly. Eg off the coast of South Africa.

As you say, the large wave creates a trough below it as it's taken energy from the wave next to it so that one isn't as high whilst the rogue one is very high and thus the seas surface to wave top height is increased further.
The occurrences off South Africa are interesting as they aren't actually driven by non-linear wave theory but in fact caused by underwater geological features combined with two currents meeting against each other.
Similar things occur with underwater geography in Nazare but much closer to the shore and are used by surfers.
