PAWNEE, Okla. — One of the largest earthquakes in Oklahoma rattled the Midwest on Saturday from Nebraska to North Texas, and likely will turn new attention to the practice of disposing oil and gas field wastewater deep underground.

The United States Geological Survey said a 5.6 magnitude earthquake happened at 7:02 a.m. CT (8:02 a.m. ET) Saturday in north-central Oklahoma, a key energy-producing region. That matches a November 2011 quake in the same region. No major damage was immediately reported.

An increase in magnitude 3.0 or greater earthquakes in Oklahoma has been linked to underground disposal of wastewater from oil and natural gas production. State regulators have asked producers to reduce wastewater disposal volumes in earthquake-prone regions of the state.

1. Little structural damage above ground.

But I wonder how all those pipelines that criss-cross Oklahoma are faring with all the shaking going on.
