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.
