Magnitude-4.5 earthquake rattles Central Oklahoma

[Jesus Malverde]

An earthquake Saturday afternoon that shook the Oklahoma City area likely was one of the largest recorded in the state's history, an Oklahoma Geological Survey seismologist said

The quake occurred at 12:10 p.m. about four miles northwest of Jones, just east of Arcadia Lake, according to the U.S. Geological Survey. It was felt in cities including Norman, Edmond, Oklahoma City and Guthrie.

The U.S. Geological Survey said it occurred about 5 miles deep. It was recorded as a magnitude-4.5 earthquake.

The Oklahoma Geological Survey measured it as a stronger, magnitude-4.8 quake

1. From March 2013: Scientists Say Oil Industry Likely Caused Largest Oklahoma Earthquake

The largest recorded earthquake in Oklahoma history was likely triggered by the injection of wastewater from oil production into wells deep beneath the earth, according to a study published Tuesday in the scientific journal Geology.

The magnitude 5.7 earthquake, which struck in 2011 near Prague in central Oklahoma, is the largest and most recent of a number of quakes scientists have tied to wastewater injection from oil and natural gas production, raising new concerns about the practice.

There is no limit to the number of ways we'll destroy ourselves, scraping the last bit of residue from our crack pipe.

2. fracking may be involved

As part of his wide-ranging research, Holland is proposing to inject pressurized water into porous rock in an area already known to be earthquake-prone, to see whether injections of oil industry wastewater are contributing to a "swarm" of earthquakes rocking the state.
