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.
The Little River Fault (see the QFFDB, Fault 556) is representative of an extensive zone of faults along the north side of the Olympic Peninsula and in the Strait of Juan de Fuca (likely connected with the fault systems at the south end of Vancouver Island, see fault database map), but these lie west of the crustal blocks that underlie the ...
Map of the Chile Rise and its fracture zones in Nazca and the Antarctic plates Active Pacific Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region. Since the map was prepared ages not shown of south-west Pacific and north Pacific Ocean floors may have been characterised.
Motion along the Mendocino Transform Fault (MTF) is right-lateral on E–W oriented, vertically dipping planes. Within the portion of North American crust overlying the Gorda slab, motion on faults is reverse, and in April 1992, a M 7.1 earthquake ruptured the southern portion of the Cascadia subduction zone. Similar to the general seismicity ...

A map displaying each of the seven major faults in the San Francisco Bay Area, and the probability of an M6.7 earthquake or higher occurring on each fault between 2003 and 2032 The slip on the San Andreas Fault which caused the 1906 San Francisco earthquake was visible in Wrights Tunnel along the South Pacific Coast Railroad after the earthquake
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 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.
