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.
San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
There is evidence that the Tacoma Fault connects with the White River River Fault (WRF) via the EPZ and Federal Way, under the Muckleshoot Basin (see map), [137] and thence to the Naches River Fault. If so, this would be a major fault system (over 185 km long), connecting the Puget Lowland with the Yakima Fold Belt on the other side of 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.
The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes. It is about 40,000 km (25,000 mi) long [ 1 ] and up to about 500 km (310 mi) wide, [ 2 ] and surrounds most of the Pacific Ocean .
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.
Major active fault zones of New Zealand showing variation in displacement vector of Pacific plate relative to Australian plate along the boundary. The Marlborough fault system (also known as Marlborough tectonic domain [2]) is a set of four large dextral strike-slip faults and other related structures in the northern part of the South Island, New Zealand, which transfer displacement between ...
Mormon Rocks is an example geological formation along the San Andreas Fault. The Pacific plate, to the west of the fault, is moving in a northwest direction while the North American plate to the east is moving toward the southwest, but relatively southeast under the influence of plate tectonics. The rate of slippage averages about 33 to 37 ...
