La Palma is indeed very interesting, but this kind of talk makes me take the author much less seriously than I would have otherwise.
Also see https://en.wikipedia.org/wiki/Cumbre_Vieja_tsunami_hazard for a good summary of the risks.
That's a pretty major factor.
Makes me question the OP. Hacked account or someone who promotes disinformation? It isn’t hard to find much better sources, so why use a trash source?
With that said, I think there's a valid point there. Even if the chances of a large tsunami hitting the east coast of NA are low (chance of having an eruption, chance of that eruption being large, and chance of that eruption causing 500km^3 of displaced earth), the amount of destruction it could cause should at least prompt some analysis as to what could be done to mitigate that damage. Especially since there are likely useful public works projects that could be done to mitigate damage from climate change anyway.
If you did public works to protect against this, then they would help you against climate change. But if you did public works to protect against climate change, they would not protect against this, because this is maybe 3 times worse. (Nobody that I have ever heard is talking about an 80 foot sea level rise from climate change.)
Mmhmm. Nothing burnishes credibility like devoting column space to how they're out to get you.
But I've heard about this threat before. It could cause massive damage. For historical reasons, an awful lot of the major US cities are on the eastern seaboard. (Of course, it could damage a lot more than just the US...)
Super-volcanoes, tsunamis, asteroids - they all happen and can be catastrophic. And La Palma is a major concern - a recent bout of activity certainly should be on the agenda for countries that would be directly affected.
But I would recommend following other sources to remain informed. Perhaps check what your local government has to offer in the way of tsunami alerts, if you think you would be affected, because checking conspiracy mongers' websites around the clock isn't a viable alternative.
