Crustal stress & geodynamics
I am building a high spatial resolution stress map of Texas and New Mexico with Mark D. Zoback of the Stanford Stress & Crustal Mechanics Group and the Stanford Center for Induced & Triggered Seismicity. We have so far 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.
We recently 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. Our stress map continues to grow, and we are currently modeling the controls to the intriguing variations that we observe.
