3.7 quake rattles northwest Oklahoma
ALVA, Okla. – An earthquake struck northwest Oklahoma Monday morning.
Around 9:17 a.m., a 3.7 magnitude quake rattled residents near Alva.
Oklahoma’s earthquakes have been linked to the injection of wastewater underground from oil and gas production and state regulators have recommended reducing the volume or shutting down some of the disposal wells.
According to the U.S. Geological Survey, Oklahoma has already had more than 90 earthquakes of magnitude 3.0 or greater this year.
