An earthquake has struck around 40 miles from Oklahoma City with a preliminary magnitude of 5.1 reported.
The Friday night quake was followed by at least two smaller tremors, the US Geological Survey (USGS) stated.
The large earthquake came at 11.24pm local time on Friday about five miles from Prague , Oklahoma, which has about 2,000 residents.
Preliminary reports from USGS said that the shaking was felt in across the state, including in major cities such as Tulsa and Oklahoma City. The tremor could also be felt across state lines as far away as Wichita, Kansas.
After the larger, initial quake, two smaller tremors were reported in the same area with magnitudes of 2.6 and 3.5, the agency noted.
USGS states that “most of North America east of the Rocky Mountains has infrequent earthquakes” but added that “most of the enormous region from the Rockies to the Atlantic can go years without an earthquake large enough to be felt, and several US states have never reported a damaging earthquake”.
