Biography
Asst. Prof. Sylvain Barbot is studying the mechanical properties of the lithosphere and faults through a combination of geodetic observations and modeling. For his PhD work, at the Scripps Institution of Oceanography at the University of California San Diego, he developed a theory to represent the short-term tectonic deformation processes accompanying earthquakes, glacier retreat, lake drainage and monsoon. His approach is implemented in “relax”, a software used, maintained and developed by the scientific community.
As a post-doctoral scholar at the California Institute of Technology, he tested the possibility of developing physical models of earthquakes that have predictive power. To that end, he developed a model of the Parkfield segment of the San Andreas Fault that incorporate the full history of faulting, including the dynamic rupture of magnitude 6 events and the slow deformation that takes place between earthquakes.
His long-term goal is to create physical models of tectonic margins evolution that can inform quantitatively of natural hazards, such as earthquakes, tsunamis and sea level rise.
Research Interests
The goal of my research is to develop a physics-based model of the earthquake cycle to assess the full range of seismic behavior that can be expected across a plate boundary.
I use remote sensing (synthetic aperture radar, GPS, optical photographs, gravity) and seismological data to investigate the mechanics the lithosphere and fault slip. These measurements can be used to constrain models of rupture and lithosphere dynamics, which include faulting, but also more distributed deformation, such as poroelastic and viscoelastic flow. An important goal of my research is to reconcile long-term (regional tectonics) and short-term (earthquake dynamics) observations and improve our capacity to predict some aspect of the earthquake cycle.
