When these stresses establishes thee continuith of rock, fracturing events, and displacement follows alongs thee fracture plane. Faults range in scale from minor dicontinuities just a few meters in extent te to major crustal presenures foresting hundreds of kilometers, such athe San Andreas Fault in California nior our the Northeh Anatoliain Fault.

Fault Influence on Pipeline Routing: Risk- Based Decision Making
