Water, the most abundant volatile in Earth’s interior, preserves the young face of our planet by catalyzing mantle convection, lubricating plate tectonics, and feeding arc volcanism. Since planetary accretion, water has been exchanged between the hydrosphere and the geosphere, but its depth... Read more
We investigate the physics underlying seismic hazards by modelling the dynamics of fault slip and plastic flow. Assimilation of deformation data from large earthquakes and exploration of mantle and fault stability allow us to better understand how the Earth deforms under stress. Our broad goal... Read more
The Megathrust Dynamics Symposium, part of the 14th International Conference on Fracture, will take place on Rhodes, Greece, in June 18-23, 2017. The symposium will gather experts in various aspects of faulting and earthquake mechanics to discuss various topics related to megathrust dynamics.... Read more
We are developing geophysical marine robots to probe the deformation of the seafloor. The end goal is to extend geodetic measurements offshore to better understand earthquakes, tectonic processes and tsunami hazards.
There is a seismic gap on the Sunda megathrust at the latitude... Read more
This project supports the work of the Earthquake Physics group and its external collaborators on fault mechanics, from tremors to giant earthquakes. We explored the nonlinear dynamics of repeating earthquakes during hundreds of cycles, the dynamics of the Indian Ocean slab as it dives below the... Read more
The goal of this research is to build a much improved understanding of seismic hazard in Sumatra using physical models of fault behaviour tuned to geophysical, geological and laboratory observations. The Sunda subduction zone, located only a few hundred kilometres southwest of Singapore,... Read more
The goal of this research is to mitigate natural hazards due to the seismic cycle – earthquake, tsunami, and sea level rise – using physical models of fault slip evolution derived from physical laws, modern geophysical data, and geological analysis. Earthquakes can cause tremendous destruction,... Read more
Large-scale inelastic properties of the lithosphere can be probed using modern geodesy techniques (InSAR and GPS) by measuring the slow deformation that follows earthquakes and changes in lake water level.
Large earthquakes on megathrusts perturb the stress of the lithosphere at great... Read more
The mechanical properties of the lithosphere control the long-term evolution of the India-Eurasia collision and affect the redistribution of stress during the earthquake cycle, impacting fault segmentation, the timing of earthquake nucleation and the initial conditions for rupture. The... Read more
