A couple of weeks and hundreds of pages ago, someone posted a link to a video of a guy who made predictions based off of US dollars folded in a certain way. He was making predictions like this for quite a few years.
2 things he said that were to come were a tsunami wiping out NYC and a missile explosion to start off the tsunami.
For the person who thought there would only be a 10ft wave....if some kind of explosion happens alongside a big volcanic eruption, the resulting tsunami would be much bigger than 10ft.
We won't know before it happens, of course.
I hope it doesn't happen, but it's best to prepare.
