There was a 3.9 magnitude earthquake about 25 miles west/southwest of Trinidad on Tuesday morning.
According to the U.S. Geological Survey website, the earthquake happened around 8:15 a.m. MT.
The USGS says that earthquakes east of the Rocky Mountains, although less frequent than in the West, are typically felt over a much broader region. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast. A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as 60 miles from where it occurred, and it infrequently causes damage near its source.
USGS reports show that shaking associated with this earthquake was weak and there was no recorded damage.
