5.1 and 3.9 magnitude earthquakes recorded in Oklahoma

A magnitude-5.1 natural disaster, the largest quake in the region in almost five years, was recorded by United States Geological Survey at 11:07 a.m. Saturday 17 miles northwest of Fairview, Okla.

The U.S.G.S. says that quake was followed by a 3.9 magnitude quake at 11:17 a.m.

The state has been recording 2.5 earthquakes daily of a magnitude 3 or greater, a rate 600 times greater than observed before 2008, the Oklahoma Geological Survey said in a report past year.

Scientists recently unveiled a new phone app called MyShake that turns Android phones into quake detecting and reporting devices.

A clerk at the Fairview Love’s Country Store said there were no injuries and no damage in the store.

The larger quake was “probably the second-largest in Oklahoma and the largest in this general area”, said John Bellini, a geophysicist at the USGS National natural disaster Information Center.

Oklahoma’s previous largest was a 5.6 natural disaster in 2011.

The quake, which struck in the northwest region of the state, is the third strongest the state has ever seen in its recorded history, ABC News reported.

Oil and gas operators in Oklahoma, where the industry is a major economic and political force, have resisted cutting back on their injections of wastewater.

Oklahoma residents were badly shaken when two earthquakes struck on Saturday morning.

It was not known if the quake was linked to oil production activities.
