My tectonics research began when I was a Ph.D. student at SMU. There, I studied the history and societal impacts of active faulting within the Enriquillo-Plantain Garden Fault Zone (EPGFZ), which is a system of left-lateral faults extending through Eastern Jamaica and Western Hispaniola. In Jamaica, I focused on neotectonic deformation within the EPGFZ. In Hispaniola, I assessed tectonic, climate, and geomorphic controls on lake flooding. As a Postdoctoral Researcher at LSU, I have focussed on understanding tectonic and climate controls on continental erosion. Now a Postdoctoral Investigator at WHOI, I am focused on testing whether far-field paleoclimate modulated sedimentation patterns and rates influence strain localization and basin geometry during the initial stages of continental rifting.
[Paper]Tectonics in Southeast Jamaica (Figure 1) is poorly understood, but the region may contain currently unknown faults that could generate large‐magnitude earthquakes. This study constrains tectonics in Southeast Jamaica by collecting and analyzing seismic and shallow sediment core data in and around Kingston Harbor. Seismic results reveal a previously unrecognized strike‐slip fault system that accommodates strain via a complex mix of compression and extension. The faults appear to be a blind extension of one major fault (i.e., The Bull Bay Strike‐Slip Fault) within the Enriquillo‐Plantain Garden Fault Zone. This fault system may represent significant hazards to Kingston Jamaica because the fault is active, located less than 5 km from the city, and a complete rupture of the fault could generate a Mw 5.8–6.9 earthquake. The analyses highlight the need for continued paleoseismic studies, both onshore and offshore Jamaica.
