LITTLE ROCK (AP) — Residents of central Arkansas are unlikely to have felt two small earthquakes that rattled the region overnight, or a third one that occurred Thursday.

The U.S. Geological Survey said Thursday that the first two quakes registered a magnitude of 2.8, while the magnitude of Thursday afternoon's quake was put at 2.7.

None of the quakes was of a magnitude likely to have been noticed by area residents.

The USGS said the epicenter of the first quake, which occurred at 11:05 p.m. Wednesday, was about 6 miles north-northwest of Quitman, in southwest Cleburne County, or about 50 miles north of Little Rock.

The second quake, according to a USGS news release, occurred at 1:55 a.m. Thursday, with its epicenter about 2 miles west of Greenbrier in Faulkner County, or 35 miles north of Little Rock.

The first two epicenters were about 18 miles apart.

A third quake was registered at 1:53 p.m. Thursday, with an epicenter about a mile from the second quake, the USGS said.
