Many 3.0-or-larger earthquakes rocked northern Oklahoma Wednesday night and early Thursday morning.
Dozens of residents called CBS Oklahoma City affiliate KWTV after feeling the long-lasting temblors. Some reported damage to or in their homes.
The U.S. Geological Survey reports a magnitude-4.7 quake was registered just before 10:30 p.m. Wednesday about 20 miles northwest of Fairview. A magnitude-4.8 quake was registered about a half mile away less than a minute later.
Quakes of that strength are considered capable of causing moderate damage, but Fairview police had no immediate reports of damage or injuries.
Dale Grant, a geophysicist with the USGS, says residents in an eight-state area probably felt those tremors.
KWTV reports they were followed by at least 11 more, ranging from magnitude 3.0 to 4.0, within hours. Several more hit earlier Wednesday.
Oklahoma has been hit with numerous small to moderate quakes recently. They've been linked to the injection of wastewater underground from oil and gas production.
State regulators have ordered reducing the volume or shutting down some of the disposal wells.
