The Juan de Fuca Ridge at northwest on map

The Juan de Fuca Ridge is a tectonic spreading center located off the coasts of the state of Washington in the United States and the province of British Columbia in Canada. This article discusses the geologic usage for the philosophical or architectural usage see Architectonics ' Or see Plate tectonics. In Plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a Washington ( is a state in the Pacific Northwest region of the United States. The United States of America —commonly referred to as the British Columbia (ˌbrɪtɨʃ kəˈlʌmbiə ( BC) ( (la Colombie-Britannique C Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page It runs northward from a transform boundary, the Blanco Fracture Zone, to a triple junction with the Nootka Fault and the Sovanco Fracture Zone. The Blanco Fracture Zone or Blanco Fault Zone (BFZ is a Transform fault zone off the coast of the Pacific Northwest of the United States which A triple junction is the point where the boundaries of three Tectonic plates meet The Nootka Fault is an active Transform fault located off Nootka Island, near Vancouver Island, British Columbia, Canada. The Sovanco Fracture Zone is a right lateral-moving Transform fault and associated Fracture zone located offshore of Vancouver Island in Canada To its east is the Juan de Fuca Plate, which together with the Gorda Plate to its south and the Explorer Plate to its north, is what remains of the once-vast Farallon Plate which has been largely subducted under the North American Plate. The Juan de Fuca Plate, named after the explorer, is a Tectonic plate arising from the Juan de Fuca Ridge, and subducting under the northerly The Gorda Plate, located beneath the Pacific Ocean off the coast of northern California, is one of the northern remnants of the Farallon Plate. The Explorer Plate is an oceanic Tectonic plate beneath the Pacific Ocean off the west coast of Vancouver Island, Canada. The Farallon Plate was an ancient Oceanic plate, which began Subducting under the west coast of the North American Plate &mdash then located in modern The North American Plate is a Tectonic plate covering most of North America, Greenland and part of Siberia. To its west is the Pacific Plate. The Pacific Plate is an oceanic Tectonic plate beneath the Pacific Ocean.
