A 4.1-magnitude earthquake shook central Oklahoma early Saturday morning following a slightly stronger earthquake the night before and amid a series of smaller quakes.
The earthquake occurred just after 5:30 a.m. local time about 19 miles north of Oklahoma City, near the Northeast Edmond Gas and Oil Field. The quake, which had a depth of about 4.1 miles, was part of a series of several earthquakes clustered together Friday and Saturday, according to the U.S. Geological Survey.
On Saturday morning, the Oklahoma Geological Survey said in a statement that there have been reports of strong shaking in the immediate area and across Oklahoma City.
State seismologist Jake Walter told USA TODAY the area has recorded about 18 earthquakes in a 12-hour span. Connecting the dots, Walter added, the quakes follow a fault identified by researchers.
