This list covers all faults and fault-systems that are either geologically important [clarification needed] or connected to prominent seismic activity. [clarification needed] It is not intended to list every notable fault, but only major fault zones.
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
Despite the rarity of strong East Coast earthquakes in the United States, they do sometimes occur. Furthermore, when these rare eastern U.S. events do occur, the areas affected by them are, on average ten times as large as western ones for events of the same magnitude. [11] Thus, earthquakes represent at least a moderate hazard to East Coast ...
Several faults run through Stanislaus County, including the Great Valley thrust fault system. The series of lines runs along the west side of the San Joaquin Valley, said Belle Philibosian, a ...
The prediction is based on research done by dozens of scientists and engineers using seismic studies, historical geological data and new information to identify nearly 500 additional fault lines ...

A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States.
