A map of the Juan de Fuca plate with noted seismic incidents, including the 2001 Nisqually earthquake. The Juan de Fuca plate is bounded on the south by the Blanco fracture zone (running northwest off the coast of Oregon), on the north by the Nootka Fault (running southwest off Nootka Island, near Vancouver Island, British Columbia) and along the west by the Pacific plate (which covers most of ...
The plates that host the fractures are Nazca, Pacific, Antarctic, Juan de Fuca and Cocos among others. Fracture zones being subducted under Southern and Central America are generally southwest–northeast oriented reflecting the relative motion of Cocos, Nazca and the Antarctic plates.
The Juan de Fuca Ridge is a mid-ocean spreading center and divergent plate boundary located off the coast of the Pacific Northwest region of North America, named after Juan de Fuca. The ridge separates the Pacific Plate to the west and the Juan de Fuca Plate to the east. It runs generally northward, with a length of approximately 500 kilometres ...
It separates the Juan de Fuca and North America plates. New Juan de Fuca plate is created offshore along the Juan de Fuca Ridge. [8] [9] The Juan de Fuca plate moves toward, and eventually is pushed under the continent (North American plate). The zone separates the Juan de Fuca plate, Explorer plate, Gorda plate, and North American plate.
These two plates converge at 3–4 centimeters per year at present. This is only about half the rate of convergence of 7 million years ago. [4] The small Juan de Fuca plate and two platelets, the Explorer plate and Gorda plate are the meager remnants of the much larger Farallon oceanic plate. The Explorer plate broke away from the Juan de Fuca ...
The western part of Washington State lies above the Cascadia subduction zone, where the Juan de Fuca plate is being subducted beneath the North American plate.The seismicity of this region consists of rare great megathrust earthquakes, like the 1700 Cascadia earthquake and more common earthquakes originating from within the subducting slab.
Juan de Fuca (10 June 1536 – 23 July 1602) [1] [2] was a Greek sailor who served Philip II of Spain.He is best known for his claim to have explored the Strait of Anián—now known as the Strait of Juan de Fuca—between Vancouver Island (now part of British Columbia, Canada) and the Olympic Peninsula (northwestern Washington state in the United States).
The Juan de Fuca plate, created at the spreading ridge southwest of the triple junction, is moving at a rate of 45.7 mm/yr at an azimuth of 244˚ in relation to the North American plate, and the Pacific plate is moving at 58.6 mm/yr in relation to the Juan de Fuca plate. [2]
