Ken Creager, the Department of Earth and Space Sciences Chair and geophysicist, is interested in earthquakes that fly under the radar instead of big, news-making quakes. Through a series of field experiments, involving the deployment of hundreds of seismometers, he has harnessed the seismic waves of thousands of tiny quakes to unravel the details of slow slip events that occur on the plate interface of the Cascadia Subduction Zone. The significance of slow-slip quakes is that they might trigger the "Big One" and they help place bounds on its eastern edge, i.e. how close the megathrust earthquakes get to the major population centers of the Pacific Northwest. He is part of a multidisciplinary field experiment to image magma under Mount St. Helens called iMUSH and is working on the West Coast-wide Shake Alert Earthquake Early Warning system. Creager has received support from the National Science Foundation for his research, and in recognition of his work, he was named a Fellow of the American Geophysical Union in 2011.
