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.
Today, the Cascadia Subduction Zone remains eerily quiet. In other subduction zones, scientists often observe small earthquakes frequently, which makes the area easier to map, according to ...
Back in North America, in 1700, a 9.0 earthquake and monster tsunami rocked the Cascadia region, an area that stretches along what would become Western Washington, Oregon and northern California ...
Japanese tsunami records, along with reconstructions of the wave moving across the ocean, put the earthquake at about 9:00 PM Pacific Time on the evening of 26 January 1700. [4] Cascadia subduction zone Sandsheet thought to have resulted from the tsunami caused by the 1700 earthquake, exposed on the bank of the Salmon River, Oregon
Jun. 20—Local leaders are focused on developing response plans for schools and communities that may be in the path of damaging tsunami waves following a Cascadia Subduction Zone earthquake. New ...
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 fault runs offshore along the West Coast from Northern California to northern Vancouver Island in Canada. It is capable of producing magnitude-9.0 earthquakes and tsunami waves about 100 feet ...
The southerly side is a transform boundary with the Pacific plate along the Mendocino Fault. The westerly side is a divergent boundary with the Pacific plate forming the Gorda Ridge . This ridge provides morphological evidence of differing spreading rates, with the northern portion of the ridge being narrow, and the southern portion being wide ...
