A series of small earthquakes struck north central Arkansas, centered near the town of Guy and Greenbrier.

The most intense tremors occurred just after 11 p.m. Central time Sunday, when a 4.7 magnitude quake hit Greenbrier. The next happened just over 17 minutes later, also centered on Greenbrier, and was magnitude 3.8. The latest happened at about 2:46 a.m. Monday, and was magnitude 3.6.

The earthquakes originated some three to four miles below the surface, according to the U.S. Geological Survey.

The Associated Press is reporting that people as far away as Oklahoma, Missouri and Tennessee felt the 4.7 temblor.

Guy and Greenbrier are near areas of extensive natural gas extraction. Some experts at the USGS, have said that could be a reason for many small earthquakes. On Feb. 16 a series of small quakes -- all under magnitude 4 -- rolled through the area around Guy.

Both towns are some 50 miles north of the capital, Little Rock. Neither is part of the New Madrid Seismic Zone, known for producing several large earthquakes in the past two centuries and thousands of small ones.
