Lewis and Geoscience Student Berry Present on Non-Equilibrium Topography and Active Fault Tectonics

Undergraduate student Allison Berry ('17) presented work she has done with Jon Lewis (Department of Geoscience) on his recently completed National Science Foundation project to understand non-equilibrium topography in southern Taiwan. Lewis presented a talk on his ongoing work with Costa Rican collaborators on active fault tectonics in Costa Rica.

Berry's research results have implications for understanding exhumation of recrystallized rocks in one of the most rapidly uplifting mountain belts on Earth. Her research was titled "The Longitudinal and Vertical Distribution of Brittle Deformation in the Southern Central Range Taiwan: Constraints from earthquakes and Mesoscale Faults."

Lewis's talk, titled "A Fault System Defines the Northeastern Margin of the Western Costa Rica Arc Sliver," was presented in a special session dedicated to the illustrious career of former GSA President Eldridge Moores. Lewis’ talk focused on recent work that he has done with Costa Rican collaborators Walter Montero and Cristina Maria Araya. They have mapped an active fault that they argue is the eastern boundary of a tectonic sliver that includes most of the Guanacaste volcanoes, and that is translating this terrane to the NW parallel to the Middle America Trench.

Undergraduate student Cate Bressers ('17) was also able to attend the national meeting in Denver. It was also a great chance to catch up with some IUP alumni in attendance. Sage Wagner, John Kearney, Joi Kiefer, and Mark Zellman were there in attendance and presenting their research.

Lewis, Berry, and Bressers also had the good fortune to attend a dinner banquet in honor of both Eldridge Moores and Walter Alvarez, two luminaries in the geosciences who told first-person stories about the Plate Tectonic Revolution as it unfolded.
