Terri Amborn and her field assistants (Crimson Rosellas) using differential GPS to survey marine terrace elevations along the Waratah fault, Cape Liptrap, Victoria, Australia, Keck Geology Consortium Undergraduate Research Project (2002).

Eli LaFromboise [L] and John Utick [R] with Dr. Marino Protti and Dr. Jeff Marshall at the Observatorio Volcanológico y Sismológico de Costa Rica (OVSICORI-UNA), Universidad Nacional, Heredia (2005).  Eli is holding a DEM image of the Costa Rican convergent plate margin.  John and Eli’s research projects examine the neotectonics of the Nicoya Peninsula (center of image), an emergent segment of the Middle America fore arc subject to rapid uplift and large subduction earthquakes (>M7.5).
