Valerie Sahakian is an academic expert in seismic hazard. Her main research goals are to characterize fault structures, better estimate ground-motion in the event of an earthquake, and to use ground-motions to understand more about past earthquakes and details of shallow Earth structure. Valerie studies active fault structures, both offshore and onshore. Some of her previous study areas include Southern California, to map fault structures and previous earthquakes in the Imperial Valley, offshore San Diego, and by the Salton Sea. Valerie’s more recent work has targeted tsunami earthquakes, such as the 2010 Mentawai earthquake. At the University of Oregon, she is assistant professor of earth sciences.
