all kinds of things can be shown with mathematical models to be “possible”, but “possible” means neither certain nor likely;
but, people love what the media (and a lot of scientists) does best - sensationalism
Like the way one type of tectonic envrionment is so freely juxtaposed with another.
There were scientists warning of the possibility of a Tohuku 9.0 earthquake before it happened, but they weren’t sensationalized - they were ignored.
You have to look at it on a case-by-case basis.
We now have multiple lines of evidence that we have underestimated the maximum quake possible on numerous faults, so it’s likely that there are others where this is the case.
On the other hand, the whole East Coast Tsunami caused by a volcano collapse IS sensationalized by the media and bad documentaries - it’s basically one scientist whose work has been debunked by the tsunami science committee as a whole, yet you still see people on FR excitedly talking about it.
