Quakes Rattle Southern Colorado, Northern New Mexico

"The largest earthquake to strike Colorado in almost 40 years" shook buildings but apparently caused little damage late last night, Denver's ABC 7 News reports. A few homes may have been damaged and some rock slides were reported.

It was a 5.3 magnitude temblor and the epicenter was "about 180 miles south of Denver."

The shaking hasn't stopped, according to the U.S. Geological Survey. It counts 12 earthquakes of 2.1-magnitude or greater in the same area since Monday afternoon.
