The USGS has confirmed a 3.7 magnitude earthquake northeast of Greeley. The earthquake started at around 9:35 pm local time on Saturday, May 31, 2014. 

According to the USGS, earthquakes east of the Rockies can be felt over an area more than ten times larger than a similar magnitude earthquake on the west coast.

"It would not be unusual for a magnitude 4.0 earthquake in eastern or central North America to be felt by a significant percentage of the population in many communities more than 60 miles from its source," the USGS website stated

Residents in the area that felt the shaking are encouraged to report their experience to the USGS on their website. You can click HERE to get fill out the "Did You Feel It" form on
