You likely didn’t feel it and it wasn’t strong enough to cause any damage.

But the U.S. Geological Survey said it detected a small earthquake Sunday night in Madison County just outside of Huntsville.

A magnitude 2.3 earthquake was detected at 9:45 p.m. Sunday, the USGS said, at a depth of about 3.3 miles below the earth's surface.

The quake's epicenter was 11.3 miles east northeast of Huntsville and 6.4 miles east southeast of the Moores Mill community.

Such small earthquakes, while maybe not common, are not unusual in north Alabama. Sunday’s quake was the second in north Alabama this year, preceded by a 2.4 magnitude event last month in Jackson County.

So far this year in Alabama, there have been 10 earthquakes – including a cluster of seven quakes in Escambia County near the Florida line. There was also a mine collapse near Birmingham in April that caused a magnitude 2.5 temblor.
