Earthquakes, Volcanoes

Expertise: Slow slip and tremor; imaging of Earth’s mantle; a lead investigator on the Imaging Magma Under St. Helens (iMUSH) project.

Through a series of field experiments, involving the deployment of hundreds of seismometers, he has harnessed the seismic waves of tens of thousands of tiny quakes to unravel the details of slow slip events that occur on the plate interface of the Cascadia Subduction Zone at depths of 25-45 kilometers. The significance of these recently discovered slow-slip quakes is that they might trigger a Big One, and that they help place bounds on the eastern edge of the Big One, i.e. how close the megathrust earthquakes get to the major populations centers of the Pacific Northwest.
