Andrew J Barbour, Ph.D.

I'm a research geophysicist in the Induced Seismicity group. My research focuses on improving our understanding of how stress changes from natural and anthropogenic sources (i.e., earthquake rupture and/or fluid injection) lead to deformation, seismicity patterns, fluid flow, and pore pressure in the Earth's crust. I am particularly interested in observations near active fault systems.
