FAIRVIEW, Okla. (AP) — Multiple earthquakes rattled Oklahoma Friday, with a 4.2 magnitude quake recorded near Fairview around 4:31 p.m. followed by a 4.1 magnitude in the same place around 5:29 p.m., according to the U.S. Geological Survey.
The USGS also reports that a 3.4 magnitude quake hit southeast of Blanchard about 2 p.m.
There were no immediate reports of damage or injuries.
The number of magnitude 3.0 or greater earthquakes has skyrocketed in Oklahoma, from a few dozen in 2012 to more than 900 last year.
Scientists link the increase to the underground disposal of wastewater from oil and gas production and state regulators have asked producers to reduce wastewater disposal volumes.
