Furthermore, the type of fault directly influences the design considerations for infrastructure. These fractures, or faults, are not merely cracks in the rock; they are critical zones where tectonic forces have been actively displacing the landmass for millions of years.

Implications for Seismic Risk Understanding an earthquake fault definition is fundamental to assessing seismic risk. At the surface, however, the evidence might be subtle.
The Mechanics of Fracture To grasp an earthquake fault definition , one must look at the mechanics of how rock deforms under immense pressure. The primary categories are determined by the relative motion of the hanging wall (the block above the fault) and the footwall (the block below).

The San Andreas Fault in California is the most iconic example, where the Pacific Plate grinds horizontally past the North American Plate. Strike-Slip Faults In strike-slip faults, the movement is predominantly horizontal.
