Summary

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 overlying sedimentary [...]

Purpose

These data are high pressure measurements of frictional properties of basement core samples from Pawnee county, Oklahoma. They provide information about the strength and stability of crustal rocks in regions of Oklahoma where induced earthquakes occur. Data are for Figure 4 of the Nature GeoScience paper.
