Assessment of seismic hazard maps

My research involves assessing the performance of earthquake hazard maps. Engineers and city planners use these maps to make decisions for hazard mitigation, but frequently the maps used prove ineffective, and there is no agreed upon metric for defining map success. My work focuses on quantifying the performance of hazard maps, so objective comparisons can be drawn between maps. Ultimately, this work can be used to ask the question of how good must a map be to be successful?

Earthquake clustering

I study large earthquake temporal clusters from a probabilistic perspective. This includes simulating paleo-earthquake records that exhibit temporal clusters to understand the broad characteristics and behavior of faults in different tectonic regimes. My research proposes an alternative to the traditional earthquake cycle model that allows a fault’s past to influence its future likelihood of experiencing an earthquake. Additionally, my research looks at qualitative intensity distributions from large historical earthquakes in California, which can facilitate a better understanding of how well current probabilistic seismic hazard assessments reflect the observed record of earthquake intensities and damage.

Midcontinent Rift

I’m interested broadly in plate tectonics and structural geology, and my research involves studying North America’s Midcontinent Rift (MCR) and how it can provide insight into the continental rifting process in general. It appears that the MCR contains many features found in other rifts as well as passive continental margins, and studying their structure as well as geophysical properties such as gravity and magnetics sheds light on their possible evolutionary paths. I’ve also been involved in working on paleo-plate tectonic reconstructions and paleomagnetics of the Precambrian, and plan to further study apparent polar wander and how changes in direction might be linked to tectonic activity such as rifting.

Seismic hazards

My research focuses on earthquakes, including both seismic hazards and what they tell us about long-term geologic processes. My previous research has included seismicity studies of lithosphere tearing and subsequent transform fault development along the Australia-Pacific subduction zone. Using Coulomb Failure Stress, b-value, and earthquake rupture property analyses, I examined the transform plate boundary development process. Currently, I am studying the seismic hazard posed by earthquakes along the eastern continental margin of North America by examining what the possible maximum earthquake magnitude might be.

Continental rifting

I’m interested in studying processes related to continental rifting by examining the North American Midcontinent Rift. Additionally, I’m interested in studying seismic hazards.
