Thesis Title:

Influence of Geometry and Deformation History on the Slip Behavior along the South Flank of Kilauea Volcano

Abstract:

The mobile south flank of Kilauea Volcano on the island of Hawaii is a mechanically complex area. Based on field observations and seismic survey results, a collection of findings reports a pattern of behavior at the south flank: fast-slip behavior (i.e., earthquakes) at the northeastern portion and slow-slip or aseismic displacement at the central portion of the south flank. The notable differences in flank morphology and deformation history at these two areas inspire the following questions: does flank geometry influence the type of slip behavior observed at each area? Alternatively, or in concert, did the removal of the ancient landslide from the embayment, alter the stress state to favor slow-slip events in this area? We use numerical simulations to examine differences in deformation behavior of the northeastern, central, and southwestern portions of Kilauea’s south flank. Our results compare well to nature in unexpected ways, with interesting implications for future south flank slip behavior. We also explore how the sudden removal of an analogue Hilina Slump from the southwestern portion of the south flank might affect the slip behavior and compare this to present-day behavior of the central portion of the south flank, which currently experiences repeating slow-slip.

For outside visitors, the best way to get to our department is to come in on Rice Blvd and turn left into entrance 20 (intersection of Rice and Kent St.). At the stop sign, you will see a visitor parking lot on your right.  From there, walk east to the department.  The google map below shows exactly where our building is.
