NORMAN — Between Jan. 1, 2012 and Dec. 1, 2012, the Oklahoma Geological Survey recorded 979 earthquakes in Oklahoma. Central and north central Oklahoma have seen the largest share of the shaking.

The state is home to five broad-band, state-of-the-art seismic stations and two backbone stations that are part of the Advanced National Seismic System, according to the latest issue of Oklahoma Geology Notes.

In the fourth quarter of 2012, the survey located 203 quakes.

Counties with the highest numbers of felt quakes include Lincoln, Oklahoma, Logan, Seminole, Kay and Payne counties.
