GIF of left-lateral strike-slip fault, showing how a near-vertical fault plane moves, causing the opposite side of the fault to move to the left. This is true no matter which side of the fault an observer is standing, hence the term “left-lateral.” Credit: Incorporated Research Institutions for Seismology
