Why has nothing been said about the earthquake that hit Colorado this morning??? According to CNN headlines, it is the largest to hit Colorado in 40 years. Two major earthquakes in the US in one day, but all you hear is about the one on the East Coast. Is there any correlation between the two quakes? Also, someone told me they heard there were other major quakes world-wide today!!! What about those? I think this story is so much larger than what hit Virginia, what about the rest of the quakes???
No other relevant recent earthquake has struck in the rest of the world, and yes, CNN has covered the 5.3 Colorado earthquake which is historical, but the earthquake also struck in a very rural region where very few people felt it, in contrast to the Virginia one felt by thousands.
A USGS scientist stated such. I trust them over, say, DHS.
I felt it in Gloucester, VA. I've never felt anything like it before. I told my husband it must be an earthquake. Very Scary!

This intraplate earthquake struck at an extreme shallow DEPTH of only 3.7 miles, get informed if you don't know about this matters.
And yes, you're right about that guy having felt the earthquake at California, that's not possible, the quake can only be felt relatively close to the New Madrid fault and California is too far from there, that's also for the clown that said he felt it in Hawaii.

There is a lot of misinformation in North America main media (left or so called right). About God and â€śGod is greatâ€ť- give me a break! Rebels are using God, as so called Canadian conservatives used God to win elections. The non believers greens -sic- (aks Zandoli here) are supporting the Ghadaffi believers. Nowdays is hard to find an independent journalist to tell the truth. In Canada, we need Who is who in the media.
lizzy phelan- misinformation about Tripoli, Aug 20, 2011
â€śThis makeshift and fluctuating army, which announces a victory every other day, has in fact been collecting defeat after defeat. Every battle recreates the same scenario, with each NATO bombardment forcing the population to flee their homes. Thus, the town is quickly run over by rebel forces who announce they have gained ground. Only then does the battle begin. The Libyan army enters the town and massacres the rebels. At that point, the population safely returns to the partially destroyed villageâ€¦..[â€¦].â€ť
