This is a short course on the subject of processing and analyzing seismic data from the EarthScope USArray facilities. The short course will be held August 25-29, 2010, at the campus of Northwestern University in Evanston, Illinois. The primary goal of this short course is to provide training to a new generation of young scientists in robust and novel methods in seismic data processing. Our aim is to inspire the participants to become future leaders in developing more effective ways to handle data from large seismic arrays, such as USArray.
