Seismo-lineament along the Dog Valley Fault Zone near Truckee, California.

The seismo-lineament analysis method is a tool to spatially correlate a shallow-focus earthquake to the surface trace of the fault that generated it. SLAM is the intellectual property and work product of Vince Cronin, and has been developed with assistance from Brandon Rasaka, Victoria Worrell, Jeremy Ashburn, Brian Bayliss, Chris Breed, Bruce Byars, Ryan Campbell, David Cleveland, Jon Cook, Kelly Cronin, Jordan Dickinson, Daniel Lancaster, Ryan Lindsay, Mark Millard, Shane Prochnow, Tyler Reed, Stephen Secrest, Lauren Seidman Robinson, Keith Sverdrup and Lisa Zygo, with funds from AAPG, Baylor University, Colorado Scientific Society, Ellis Exploration, Ft. Worth Geological Society, Geological Society of America, GCAGS, Samson Resources, Roy Shlemon Scholarship Fund, Sigma Xi, and SIPES.
