The Department of Earth and Atmospheric Sciences continues its Fall Seminar Series with a geology seminar at 3:10 p.m. on Tuesday, Nov. 14, in Room 206, O’Neil Hall.
Visiting speaker John Wakabayashi, Ph.D., professor at California State University, Fresno, will present with “"Insight into Subduction Interface Processes from Exhumed Subduction Complex Rocks: Localization of Megathrust and Exhumation Slip.” The seminar focuses on what exhumed rock from a subduction zone can tell us about the nature of seismic slips which go on to produce faults, shear zones and penetrative strain. To illustrate these various outcomes, Wakabayashi looks at accretionary and non-accretionary megathrust in two unique areas of initiation - the Franciscan Complex, Northern California, and Sanbagawa Belt, Japan.
Wakabayashi's areas of specialty include the study of tectonic geomorphology, basement tectonics and subduction initiation. This also includes the long term developments found in strike-slip fault systems such as the San Andreas Fault. He has also delivered international keynote talks on tectonic geomorphology for the Geological Society of America Penrose Conference in Urumqi, China, as well as the Geological Society of London in London, England.
