Kris Walker
Biography
Kris Walker started at IGPP in Oct. 2003 as a Post Graduate Researcher.
He received his bachelor's degree in geophysics from the University of
Delaware in 1998, and his master's and doctorate degree in geophysics from
Stanford University in 2000 and 2003, respectively. As a student, he
cultivated an interest in applying both active- and passive-source
seismological techniques to studying tectonic and geodynamic processes at
lithospheric scales. Working with Mark Zumberge and Peter Shearer, Kris
is now looking at ways to combine global seismic and infrasound data to
search for natural and anthropogenic events that emit energy into the
Earth's atmosphere and crust. Potential sources include meteorite
impacts, explosive volcanic eruptions, and nuclear explosions.
Kris Walker is also working with Mark Zumberge and John Blum in testing the
Optical Fiber Infrasound Sensor (OFIS) located at Piñon Flat Observatory.
Their goal is to find the best method for calculating the backazimuth to a
specific event, and the optimum number and orientation of OFIS's in order
to make this calculation.
