what boundary is the juan de fuca plate
Juan de Fuca Plate 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 Pacific Ocean and is the largest of Earth's tectonic plates). The Juan de Fuca plate itself has since fractured into three pieces, and the name is applied to the entire plate in some references, but in others only to the central portion. The three fragments are differentiated as such: the piece to the south is known as the Gorda Plate and the piece to the north is known as the Explorer Plate. The separate pieces are demarcated by the large offsets of the undersea spreading zone.
Tierra del Fuego The name Tierra del Fuego derives from the Portuguese explorer Ferdinand Magellan[clarification needed]; sailing for the Spanish Crown, in 1520 he was the first European to visit these lands. He believed he was seeing the many fires (fuego in Spanish) of the Yaghan, which were visible from the sea, and that the "Indians" were waiting in the forests to ambush his armada.[3]
