Research Interests

Dr. Duan's current research interests focus on earthquake source physics, particularly earthquake rupture dynamics on geometrically complex fault systems within complex geologic structures, and extend to physics-based strong ground motion prediction and seismic hazard analysis. He has developed an explicit Finite Element Method code (EQdyna) and has applied it to explore physical controls on earthquake dynamic rupture propagation, response of fault zones to nearby earthquakes, and physical limits on ground motion. Collaborating with colleagues in computer science, he parallelizes EQdyna using a hybrid MPI/OpenMP approach to make use of modern computer clusters. He is also interested in unifying the dynamic model and the quasi-static deformation model to study earthquake cycles in realistically complex fault systems, and seismic & geomechanical modeling for reservoir characterization.
