Surface Faults An earthquake fault definition distinguishes between the subsurface reality and the surface expression. Classification of Fault Movement Not all faults move in the same manner, which is why a detailed earthquake fault definition includes specific classifications based on the direction of slip.
Earthquake Fault Definition and the Role of Tectonic Forces
These movements dictate the type of seismic hazard a region might face. The fault zone itself extends deep into the crust and can be hundreds of meters wide, filled with crushed and fractured rock known as fault gouge.
Strike-Slip Faults In strike-slip faults, the movement is predominantly horizontal. An earthquake fault definition begins with understanding that the Earth’s crust is fractured into numerous segments.

At the surface, however, the evidence might be subtle. The blocks on either side of the fault slide past one another sideways, with little to no vertical motion.
