Faults are different from fault lines. A fault is a three-dimensional surface within the planet that might extend up to the surface or might be completely buried. In contrast, a fault line is where the fault cuts the Earth's surface… if indeed it does.(b) Major faults (thick red lines) from Elliott and Freymueller (2020), except for the Hines Creek Fault and the Northern Foothills Thrust Belt (NFTB) which are from Benowitz et al.
