Recent widespread seismicity in Oklahoma is attributed to the reactivation of pre existing, critically-stressed, and seismically unstable faults due to decades of wastewater injection. However, the structure and properties of the reactivated faults remain concealed by the sedimentary cover. Here, we explore the major ingredients needed to induce earthquakes in Oklahoma by characterizing basement faults in the field, in seismic surveys and via rock mechanics experiments. Outcrop and satellite mapping reveal widespread fracture/fault systems with trends that display a marked similarity to the trends of recent earthquake lineaments. Our 3D seismic analyses show steeply-dipping basement-rooted faults that penetrate...

The data are time series of laboratory strength and permeability measurements of 5 rock types. The tests were conducted as part of an interlaboratory comparison to determine repeatability of measurements using different test equipment and measurement techniques. These data represent the USGS contribution to the study. Other contributing organizations are archiving data sets separately.
