MAYNARD, Ark. (KAIT) - Within 36 hours, the U.S. Geological Survey recorded multiple earthquakes near Maynard. And that number seems to be growing.

The USGS reported the first M 2.6 quake Tuesday, Oct. 6, at 9:11 a.m. Central Daylight Time about four miles east-northeast of Maynard.

Since then, as of 1 p.m. Wednesday, Oct. 7, the office has added at least five more quakes, including a 2.5 measured on Monday but just posted on Wednesday:

“The area surrounding the [New Madrid Seismic Zone] to the north and west in Arkansas, Missouri and Illinois has had a history of scattered earthquake activity,” Dr. Steve Horton, Research Scientist with Memphis' Center for Earthquake Research and Information said. “It is sometimes thought of as a halo of seismicity around the NMSZ. I think the Maynard earthquakes fit in that category. More specifically, I can say that they are 5-12.8km deep; too deep to be man-made, so they are natural earthquakes.”
