Overview:

I received a Master of Science degree in 1991 from the Earth Sciences Department at the University of California, Santa Cruz. My thesis focuses on the coastal neotectonics and earthquake hazards of the Nicoya Peninsula along the Pacific convergent margin of Costa Rica, Central America.

This research project included a field investigation of uplifted late Pleistocene and Holocene marine terraces, dislocation modeling of coseismic uplift patterns along the peninsula’s coastlines, and a study of eyewitness accounts documenting the geologic effects of the M7.7 1950 Nicoya Earthquake.
