Ruth Harris

My current research focuses on understanding large earthquakes, what causes them to start and stop, and determining how they generate strong ground shaking.  My approach involves computer simulations of earthquake rupture dynamics, and investigations of geophysical and geological field and laboratory observations.


Ruth Harris is a member of the Earthquake Science Center and she is the chief of the 30-scientists Earthquake Processes, Probabilities, and Occurrence Megaproject.

She leads a USGS project investigating physics-based earthquake rupture in heterogeneous fault zones and a SCEC-USGS project testing earthquake simulation codes.

Previous science accomplishments include:

     *development of the stress shadow hypothesis and coining of the "stress shadow" term, with R. Simpson

     *the first simulations of dynamic multi-fault earthquake rupture, with S. Day and R. Archuleta

     *the first simulations of bimaterial rupture, with results that can produce supershear rupture speeds, with S. Day

     *the first imaging of the Juan de Fuca plate subducted at depth beneath southern Oregon, with H.M. Iyer and P. Dawson

     *the first detailed inversions of geodetic data for 2D slip on a fault, with P. Segall
