How to determine principal stress axes from a fault using a stereonet

This video is a step-by-step guide to finding the maximum, intermediate, and minimum principal stress axes (commonly referred to as sigma-1, sigma-2, and sigma-3 respectively) from a given fault orientation (strike/dip of 070/60) and a slip lineation (rake of 90). This video is designed with college-level structural geology students in mind. 0:00 Plot the fault plane & slip lineation 2:27 Visualize the fault & check your work 3:25 Find the maximum principal stress axis 6:56 Find the minimum principal stress axis 8:06 Find the intermediate principal stress axis Additional resources: Basic Methods of Structural Geology by Stephen Marshak and Gautam Mitra, Chapter 12 Analysis of Fracture Array Geometry The textbook used for this class: Structural Geology by Haakon Fossen ABOUT ME: 👋 I’m Allison, a structural geologist and Earth Science educator in Northern California.
