|Colorado & Virginia quakes just hours apart|
With the enormous 5.9 earthquake that was felt across the US east coast today, its important to note that a Magnitude 5.3 quake was felt only hours before in Colorado. The Colorado quake is just as rare as the East Coast quake. Colorado has not felt that kind of activity since 1967 when a magnitude 5.3 struck near Denver and another followed it in 1973 with a 5.7 in the northwest corner of the state. Mining is blamed on those quakes. The Appalachian mountains are currently undergoing a large amount of surface mining. Could there be a correlation?
