Colorado experienced its third earthquake since Sunday as a small 2.7 magnitude quake occurred early Wednesday morning. According to the U.S. Geological Survey, the latest quake occurred in the same area as the temblor Monday night with the epicenter 11 miles north of Craig.

The latest quake was recorded at 1:58am and was centered 3.1 miles below the surface, much like the previous one in the Craig area. While the temblor was small enough that it most likely wasn’t felt, the recent quakes have garnered the attention of seismologists and geologists in the state.

Earthquakes in Colorado are not unusual as the USGS says nine were recorded this year and more than 100 in the last four years. However having this many in such a short time span is not particularly common. The last time the state experienced two quakes of magnitude 3.5 or greater so frequently was in 2001 when an earthquake “swarm” shook the area near Trinidad. During that event, from August 28 and September 21 of that year, 12 earthquakes of magnitude 2.8 to 4.6 struck just west of the southern Colorado city.
