  • Probabilities and Seismic Hazard Analysis - Spring 2013, 2015
  • Seminar in Seismology - Fall 2014
Research Goals:

My goal is to contribute to the improvement of our understanding of seismic hazard and loss in the central U.S., the nation, and the world, and to credibly communicate this understanding to earth science professionals, engineers, emergency response planners, private industry, and the general public.

Research Overview:

  • Probabilistic and Scenario Seismic Hazard and Risk Analysis
  • Earthquake Strong Ground Motion and Site Effects
  • Uncertainty in Hazard and Loss Estimates
  • Magnitudes of Historic Earthquakes from Intensity Observations
  • Seismology, including Downhole Seismology
  • Tectonics

Current and Recent Research Projects

  • Empirical Eastern North America Ground Motion Prediction Equations (GMPEs)
  • Ground Motion Intensity Modeling for the 1811-1812 New Madrid Earthquakes
  • Memphis, TN, St. Louis, MO, and Charleston, SC, Urban Seismic Hazard Mapping
  • Effect of the Upper Mississippi Embayment on Seismic Hazard Modeling
  • CEUS ground motion database for soil and rock (various soil conditions)
  • Q boundary and regional Q studies in ENA
