characteristics of the earthquake fault lines
Characteristics of the San Andreas Fault Zone. The surface expression of the San Andreas transform fault zone is a right-lateral strike-slip fault. The fault zone is approximately 1300 km long and is made up of three major segments, each with characteristic types, magnitudes and frequencies of earthquake activity.he relative rate of motion between the North American plate and the Pacific plate is approximately 3.5 to 4.6 cm per year, most of which (2.0 to 3.5 cm per year) is accounted for by horizontal displacement along the San Andreas fault zone.
