Pair of Quakes Rattle Central Portions of Oklahoma

Two earthquakes have rattled portions of Oklahoma that are becoming accustomed to experiencing many of the temblors.

The U.S. Geological Survey recorded a 3.4 magnitude quake near Medford Sunday. Shortly before that, the survey recorded a 2.5 magnitude quake near the town of Perry.

Oklahoma has become one of the most earthquake-prone areas in the world, with the number of quakes magnitude 3.0 skyrocketing from a few dozen in 2012 to more than 720 so far this year.

Many of the earthquakes are occurring in swarms in areas where injection wells pump salty wastewater, a byproduct of oil and gas production, deep into the earth.
