Dr. Boyd

Teaching

I give lectures on time-dependent seismic hazards and stresses before, during, and after earthquakes.

Research Overview
Much of my past research has focused on the physics of deformation of mantle minerals and aggregates at seismic frequencies and elevated pressures and temperatures. My past research has also included the measurement and interpretation of seismic attributes in the lithospheric mantle beneath mountain ranges and large strike-slip faults. Currently, my research involves many aspects of probabilistic seismic hazard analysis (PSHA), particularly for intraplate regions such as the central and eastern United States, and includes time-dependent earthquake probabilities, ground motion prediction equations, and earthquake clustering.
