Measuring the aspect ratio of pseudotachylyte injection veins, Santa Rosa Mylonite Zone
The Earthquake Processes research group at McGill incorporates seismology, numerical and theoretical modeling, structural geology, field mapping, and minerology in the study of fault geometry and slip behaviours. We address questions about rheology, spatial and temporal controls on fault creep, tremor and earthquakes, mineral- earthquake interactions and the role of fluids.
See faculty websites for more information about other research interests, including volcano seismology (Harrington), marine geology and inversion tectonics (Kirkpatrick), soft sediment deformation and ore deposits (although usually not at the same time; Rowe), subducting seamounts and glacier sliding (Liu).
Potential students and postdocs: If you are interested in joining our group, contact any of the faculty members by email. Also see Christie's information for prospective applicants.

Winter 2019: Welcome to the group: PhD student Inga Boianju, Undergraduates Audrey Woo and Ava Ghods (John Abbott)
Fall 2018: Ge Li has shown that the Leech River Fault on Vancouver Island correlates with a wide (10 km) zone of seismic activity above the subducting plate interface Li, Liu, Regalla and Morell 2018 GRL. Kelian published the biggest ever compilation of fault roughness data to examine scaling relationships and roughness evolution: Dascher-Coursineau et al. 2018 JGR. John showed that stress drops of earthquakes inside the Charlevoix impact structure are greater than stress drops outside the structure, possibly reflecting different fault properties. He also won the EPS department poster competition for this work! (Onwuemeka et al. GRL 2018)
Welcoming new students Sam Metteer and Tim Howell to the Rowe group! Sam will work on fault strengthening after earthquakes and Tim will study the effects of structural deformation on a metamorphosed ore deposit.
Recent graduate Kelian Daschier-Cousineau has been awarded the 2018 Jack Henderson Award for Best MS Thesis from a Canadian University by the Canadian Tectonics Group. Congratulations Kelian and his advisor Jamie!
