Research Areas

Overview

Seismology research and machine learning applications to earthquakes across Texas, New Mexico, California and Finland. Current projects include earthquake source characterization, mitigation of injection induced seismicity, using near-surface geophysics to study climate change, and geothermal well risk monitoring. Field campaigns in Texas and New Mexico, and opportunities to work with multiple geophysical techniques.

Study Maps Stress Changes Around Fault Activated by Hydraulic Fracturing

Researchers were able to observe stress changes before and during an earthquake induced by hydraulic fracturing in Alberta, Canada, with the help of a phenomenon called seismic anisotropy.
