I found this statement in " AnIn "An Introduction to Seismology, Earthquakes and Earth Structure" Author(s): Seth Stein, authors Seth Stein and Michael Wysession
made the statement: "Faulting will occur along the plane where the shear stress is the highest". However, no further clarification was given.
Please explain whether What are the implications of this statement is? Is the statement true or false.? What are the processes that cause faulting to occur along the plane of maximum shear stress?
