Now I've read several articles of this and viewed some YouTube vids on this topic, too. There have actually been many different people posting about an Atlantic asteroid impact, from the articles on Russia to self-proclaimed profits, to alien abductees who were told by an alien for whatever reason.
What I DO find interesting is that the US military and several agencies moved AWAY from the East coast from Spring through Fall in 2015. The military maneuvers took place during this time under the name of Jade Helm and under the guise of military training for social unrest situations. Literally hundreds of photos flooded the internet, photos of military equipment being relocated en mass. I don't mean a train here or there, but HUGE amounts of equipment (tanks, trucks, you name it). All moved quite far West. Mostly West of the Mississippi.
Portable morgue stations were placed in a radius around the Mississippi river. Why would the two be connected, you might ask? Because if there were a big asteroid that might be projected to hit in an area that would present a tsunami that was going to go into the gulf of Mexico, then perhaps the river would be flooded and cause wide casualties.
Not to mention the strange WalMart closings and "retrofitting" of plumbing all of a sudden. However, reports came out of there, that the Walmarts appeared to be staging centers, and were cleared out entirely of merchandise and had guard towers inside. That's just reports, unconfirmed, but going to mention it anyway.
As for a timeline for this asteroid, some reports are pointing to December 2015. But we all know how dates go, right? They come and go and we have all seen the world end every other month as a new prediction with a specific date announced. That's okay. We can speculate.
So as the December timeline approaches, we also have the entire North American Craton MOVING...from June on in through December as I've seen...triggering EQ storms.
Just because an asteroid hits, doesn't mean that other things cannot happen simultaneously or as a result of the doom. We are NOT on a stable planet. Events can be numerous simultaneously and right now there is massive unrest.
