So yea, these are legit scientists saying this. Nothing conspiracy about this. This is going to be on par with Fukushima. If you haven't seen the damage done there, yikes.
Now we can get weird about it and throw HAARP into this and say well, the gov'ment is going to make this happen but this is based on patterns that happen and have happened for 1000's of years. Even if they do have the tech and power to make these things happen, there is already scientific proof that it will eventually snap and cave in.
Then we can even look at this as being fear propaganda, ya know, cause fear is how people get controlled the easiest. If they want people out of that area, why not scare them out?
Either way, things like this have been getting worse over the last 100 years and I don't see it getting better.
