A 4.6-magnitude earthquake struck Monday morning about 10:22 a.m. 4 miles south of Bedrock, Colorado. Several residents in Moab and Monticello have felt the quake. Over 650 reports of felt shaking have already been received by USGS.
The M4.6 earthquake was very shallow (0.8 km) and felt over a wide area with more than 659 people reporting feeling some shakings in Utah and Colorado.
The USGS initially reported the quake was 5.3 magnitude, before quickly downgrading it to 4.6. TOO STRONG TO BE TRUE? Such earthquakes happen very rarely in Colorado! The largest recent earthquake was a M5.3 in 2011.
