Abstract: Seismotectonic analysis for engineered structures is critical along the West coast. Volcanic regions offer unique challenges to understanding active faulting. The southern Cascades is a region in which domains of collisional tectonics, arc extension, and transform related transtension come together and rapidly evolve. On top of this, dike intrusion causes spectacular fault offsets over short rupture lengths. We will look at examples of volcanic seismotectonics in the Hat Creek graben region, and discuss the difficulties in developing a coherent tectonic picture.
Speaker Bio: Dr. Marcus Bursik - Currently chairman of the Geology department at UB. Ph.D. from Caltech on “Volcanotectonic evolution of the Mono Basin, California,” in 1989. Came to UB in 1992, after post-doctoral research at University of Cambridge and Jet Propulsion Laboratory. Research has included volcanic seismotectonics since that time with both field work and satellite geodesy, and participation in numerous related initiatives, campaigns and boards.
