Crustal stress & geodynamics
As part of my work at the Stanford Stress & Crustal Mechanics Group and the Stanford Center for Induced & Triggered Seismicity, I am working with Mark D. Zoback to build a high spatial resolution stress map of the south-central USA. We have compiled some 300 new high-quality stress orientations through partnerships with industry, and we are also mapping faulting regime (relative principal stress magnitudes). Our new data show a surprisingly variable stress field across the region, which provides an opportunity to understand the contribution of tectonic and local, geodynamic factors to stress perturbations.
In 2016, we published a paper in Geophysical Research Letters presenting our first 200 stress orientations. The results show a surprisingly variable but coherent stress field across the area. In 2018, we added some 100 more stress orientations in the prolific Permian Basin of west Texas and southeast New Mexico. Our stress map continues to grow, and we are currently working to understand the intriguing variations that we observe across the south-central USA.
