North Texas earthquakes occurring on faults not active for 300 million years

Study by Beatrice Magnani, USGS and other SMU scientists shows recent seismicity in Fort Worth Basin occurred on faults not active for 300 million years. The study indicates reactivation of long-dormant faults as a consequence of waste fluid injection. Recent...

Study links Raton Basin earthquakes to oil and gas fluid injections, again

A rash of earthquakes in southern Colorado and northern New Mexico recorded between 2008 and 2010 was likely due to fluids pumped deep underground during oil and gas wastewater disposal, says a new University of Colorado Boulder study. The study, which took place in...

Visualizing spills data from unconventional oil and gas activity

Study finds 6 600 spills from fracking in just four US states

Each year, 2 to 16 percent of hydraulically fractured oil and gas wells spill hydrocarbons, chemical-laden water, hydraulic fracturing fluids and other substances, according to a study published yesterday in Environmental Science & Technology. The analysis,...

Oklahoma's M5.8 earthquake activated an unknown fault

USGS Geophysicist Daniel McNamara said that September 3, 2016 Mw5.8 Pawnee, Oklahoma earthquake was not on a fault known by the USGS. Instead, it happened on a fault perpendicular which intersected the fault. Based on aftershock patterns, this one is an unknown...
