Paul Segall is the Cecil H. and Ida M. Green Professor of Geophysics at Stanford University, specializing in active earthquake and volcanic processes through geodetic data analysis and physics-based modeling of crustal deformation.
Education:
- Ph.D. in Geology, Stanford University (1981)
- M.S. in Earth Sciences, Case Western Reserve University (1976)
- B.S. in Earth Sciences, Case Western Reserve University (1976)
His research integrates precise GPS positioning and InSAR measurements to invert deformation data for fault and magma chamber geometry, slip-rate variations, and dilation processes. Key focus areas include plate boundary dynamics (San Andreas, Cascadia, Japanese subduction zones), earthquake nucleation mechanisms, slow slip events, induced seismicity, and magma migration physics. Methodologies draw from solid and fluid dynamics to develop predictive hazard models.
Recent publications (2023-2024) reveal intensive work on physics-based volcanic deformation modeling, caldera collapse earthquake mechanics, and dike propagation dynamics. These studies emphasize coupled processes (magma flow-fracture-elasticity interactions) and stress-driven seismicity patterns, with strong multi-institutional collaboration for model validation in volcanic hazard forecasting.
Segall leads the Crustal Deformation and Fault Mechanics research group, which investigates strain accumulation between earthquakes for seismic hazard assessment and magma-induced surface inflation for eruption forecasting through integrated observational and theoretical approaches.
