5.1 and 3.9 magnitude earthquakes recorded in Oklahoma

A 5.1 magnitude earthquake shook northwest Oklahoma and was felt in seven other states on Saturday, the U.S. Geological Survey said, the third-largest temblor ever recorded in the state where the power and frequency of earthquakes has dramatically increased in recent years. The earthquake centered about 17 miles north of Fairview in northwestern Oklahoma occurred at 11:07 a.m. and was reportedly felt across Arkansas, Iowa, Kansas, Missouri, Nebraska, New Mexico and Texas, the USGS said. A second quake measured at 3.9 magnitude struck ten minutes later, followed at 11:41 a.m. by a 2.5 magnitude quake. Both were in the same area of the larger temblor and about 100 miles northwest of Oklahoma City.
