Christine Regalla

About

Dr. Christine Regalla is an Associate Professor in the School of Earth and Sustainability at Northern Arizona University, where she has been a faculty member since 2019, recently promoted to Associate Professor in 2024. She is a field geologist whose research centers on understanding where, when, and how faults accommodate active deformation and seismicity.

Research Interests

• How the landscape response to fault slip can be used to compliment paleo-seismic and seismic records to characterize the slip history of seismogenic and tsunamigenic faults in onshore and offshore environments.
• How temporal and spatial patterns of deformation can be used to interpret the dynamics of lithospheric-scale deformation.
• How outcrop-scale to micro-scale deformation can be used to investigate processes that lead to seismic slip

Education

• Ph.D. Geosciences, Pennsylvania State University (2013)
• M.S. Geosciences, Pennsylvania State University (2009)
• B.S. Earth and Environmental Sciences, Lehigh University (2005)
