“…Earthquakes clearly delineate an approximately 70°southeast-dipping fault structure, consistent with the RMT modeled dip of the inferred nodal plane of the 13 February M w 5.1 earthquake (Figures 2a and 2b). Earthquake source depths show that most of the seismicity occurs in the basement at depth of 6-9 km below mean sea level, roughly 3.5-6.5 km below the Arbuckle-Precambrian interface (~2.5 km) [Campbell and Weber, 2006]. The relocated depth of the 13 February M w 5.1 is 9.1 ± 1.0 km, placing the largest event in the sequence at the base of the seismicity (Figures 2b and 2c).…”

The Mw 5.1 Fairview, Oklahoma, earthquake on 13 February 2016 and its associated seismicity produced the largest moment release in the central and eastern United States since the 2011 Mw 5.7 Prague, Oklahoma, earthquake sequence and is one of the largest earthquakes potentially linked to wastewater injection. This energetic sequence has produced five earthquakes with Mw 4.4 or larger. Almost all of these earthquakes occur in Precambrian basement on a partially unmapped 14 km long fault. Regional injection into the Arbuckle Group increased approximately sevenfold in the 36 months prior to the start of the sequence (January 2015). We suggest far‐field pressurization from clustered, high‐rate wells greater than 12 km from this sequence induced these earthquakes. As compared to the Fairview sequence, seismicity is diffuse near high‐rate wells, where pressure changes are expected to be largest. This points to the critical role that preexisting faults play in the occurrence of large induced earthquakes.

“…We assess the validity of our velocity model by calculating selected Pg arrival travel times and comparing them to prestack data. We define our 3‐D raytracing model space as two layers separated by a basement interface derived from basement depth data from wells (Campbell & Weber, 2006). A 1‐D velocity model for the sedimentary layer (Darold et al., 2015) and our final 3‐D velocity model are used to populate the layers with P‐wave velocities.…”

The study of Precambrian rocks in the midcontinent region (Figure 1) of North America is crucial in understanding the Proterozoic evolution of the North American continental lithosphere. Due to the limited exposures of the Precambrian crystalline rocks in the midcontinent region, most studies have used cores and drill cuttings to study the Precambrian geology in this region. In Oklahoma, the Precambrian basement is covered by Phanerozoic sediments except for a small area in Spavinaw, OK in the northeast and in the eastern Arbuckle mountains in the southeast. Some of the early petrological and geochronological studies of the Precambrian basement rocks laid the groundwork for investigating the continental evolution in the midcontinent region (
