The U.S. Geological Survey says four more small earthquakes were recorded Oct. 15 in northern Faulkner County, Arkansas.
According to a list of earthquakes on the USGS Web site, the earliest quake recorded was one of magnitude 3.8 at 5:20 a.m., about two miles south of Guy. Next came a magnitude 2.4 quake at 7:19 a.m., about three miles south of Guy. That was followed by a magnitude 3.0 quake at 1:40 p.m., three miles northeast of Greenbrier, and a quake of magnitude 2.0 at 4:02 p.m., two miles south of Guy.

Researchers say quakes of 2.5 to 3.0 magnitude are typically the smallest felt by humans.
