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.
