A magnitude 2.7 earthquake centered near Fenton, Mo., shook the St. Louis region around 6:25 a.m. today.

According to the U.S. Geological Society, the quake emerged from an area about three miles below the surface.

People in the St. Louis market said they could feel the shaking, but it was not as apparent on the Illinois side of the Mississippi River.

There have been no reports of damage.

Last month, a magnitude 5.2 earthquake shook much of the Midwest. Its epicenter was near West Salem, Ill., near the Indiana border. More than two dozen aftershocks followed that quake, including some registering 4.0 magnitude and higher. Seismologists say the aftershocks were nothing unusual.

The St. Louis region sits along the New Madrid fault line.
