Ken Hudnut applies new technologies such as GPS and lidar to earthquake research as a geophysicist for the USGS in Pasadena, California. To help understand the San Andreas fault system and earthquake source physics, he has studied earthquakes worldwide using satellite & airborne imagery analysis along with field work to provide ground truth. He led the earthquake source design for the ShakeOut scenario, a magnitude 7.8 earthquake on the San Andreas fault enacted by over 5.5 million people in Nov. 2008 and more people annually since then. As project manager for the GPS L1C signal design since 2003 and GPS SLR team member, his contributions to GPS modernization received recognition from NASA, GPS World, and Institute of Navigation. Before joining USGS in 1992, he was a post-doctoral fellow at the California Institute of Technology Seismological Laboratory. He received his Ph.D. from Columbia in 1989, and his A.B. (high honors) from Dartmouth in 1983. He is a Visiting Associate in Geophysics on the faculty of the California Institute of Technology.
